I wanna like the Legion but I really cant defend them in their current incarnation I am always told "Bro the cut content bro Bethesda forced them to be evil bro" and the problem is you can make the Legion look so much better easily. I think most of the problems stem from Caesar himself the dude is straight up a retard who read half a history book. However, at the same time I cant help but be amazed how just how much more intelligent the Legion is compared to the NCR. Most of the Legion Quests are just Caesar telling you "Okay so we have been in contact with this organization before or we currently doing this plan just go help them please" compared to the NCRs "Courier please everyone hates us these tribal larpers are always one step ahead of us oh my god I think the rocks are speaking latin"
I think my problem is the Legion feels much more like Sparta than Rome the dislike of technology never really rubbed me the right way since the Legion is shown to use technology (some legionaries use guns, power fists, and the howitzer) or really advanced tactics when fighting the NCR (Frumentaris basically insert themselves into almost every facet of the Mojave, years of planning, psyops, disinformation warfare). Compared to the tactics the NCR use under Oliver they downright look like savage tribals with guns compared to the Legion.
Personally, my 3 major things to fixing the Legion have got to be slaves can earn their freedom through hard work, forget the hate boner over technology Rome was so strong since they pushed for advancement in both military and society, and maybe introduce an Octavian of sorts where he wants to reform the Legion for the better but still stay true to the ideals of Rome.
I think that was the point. Edward Sallow is a smart guy, but he only read parts of books instead of getting not only the full story but also the context behind the books he was reading. He's what we call a "Sophos Moros", or a "wise fool". He's wise when compared to the average barbarian or politician, but he's an intellectual dilettante when compared to real intellectuals. His appeal, in the end, lies in the ultra-nationalist and hardcore warrior ways of his faction, and their utter hatred for anything that reeks of degeneracy.
And I also think the Legion is a victim of what one of my friends call "Hollywood Rome", that is, a movie-based view of the Roman Empire as this center of power and civilization through simple tyranny and military might, looking over parts of Roman history where piety, propriety, family values, and good manners were once a part of Roman life. The writers of FNV based the Legion not on the real Rome, but on Hollywood's version of Rome, a version of Rome created by people who saw it as nothing more but a tyrant state full of slavery and militarism, a version far unlike the real Rome which had complex political issues before, during and after the Imperial period.
But yeah, compared to the NCR, who basically are about as bureaucratically efficient as the fucking Imperium of Man, the Legion stands head and shoulders above them. The NCR is a liberal democracy that's drowning in red tape and infighting so badly that some intellectual dilettante and his tribe of Roman cosplayers are running rings around them just because he knows how to inspire people and properly run a bureaucracy AND an army. You look at the NCR soldiers, and Chief Hanlon even states that not all of them have proper service rifles or armor. They're literally at the same state the Russian army was in WWI, where there were more people than rifles, and in the five years since they kicked out Joshua Graham from Hoover Dam, they've done nothing but lose thousands of people to Legion attacks and attacks from random gangs and crooks.
If I were writing the story, I would have written in that the Legion lost its primitivism after Joshua Graham lost at Hoover Dam. They would actually take in Enclave remnants from the FO3 Enclave. Like say, they fled the carnage in Washington DC in disgrace, or they got lost and never made it to Washington DC in the first place, then after the First Battle of Hoover Dam, they came across the Legion, and when Caesar recognized who they were, he offers them an honored place in his Legion, and he starts integrating them into the Legion and getting them to work producing energy weapons and power armor for his men to make up for Joshua Graham's defeat at Hoover Dam, with them reactivating old factories in Legion turf for that purpose.
I would have the game at first show the Legion to be primitive, with most Legion scouts and recruits you meet having the same primitive weapons and armor as in the base game, and even have the NCR guys talk about how the Legion in the last war only used rudimentary guns and explosives as the height of their tech. Then I would surprise the player by having Legion elite troopers show up decked in Fallout 3 Enclave power armors shouting "AVE, CAESAR!" while holding aloft their thermic lances and laser/plasma rifles when the Courier goes to Caesar's camp and he gives a speech about how they're going to win this time.
And as the Courier looks over the sea of men in black power armor yelling "AVE, TRUE TO CAESAR!" it's hard to argue with that idea, making the NCR campaign all the more harder, especially when a platoon of these Legion/Enclave troopers storm an NCR position and easily kill everyone there, even the Rangers. It gets so bad to the point where after this gets revealed, the NCR responds by offering pardons to Enclave and Brotherhood remnants within their own territory who haven't yet joined the Legion, so they can get advanced power armor and energy weapons training/production for their own troops.
Of course, if you go the Mr. House or Yes Man route, these power-armored Legion/Enclave boys run into fully-upgraded Securitrons, and they just get fucking peppered with rockets and grenades meant for tanks, so it's not like this will change those routes that much.
