I'm gonna enjoy tearing you a few new assholes.
You keep insisting that the game was "designed" with crits in mind, and no, it wasn't.
Yes, it was. One of the fucking Soldier achievements literally requires you to shoot two random critical rockets in a row.
That alone won't convince you, I'm sure, so let me break down the numbers for you:
A full critical shotgun blast (180) does JUST enough damage to kill a Pyro/Demoman (175) and just barely misses a full HP Soldier (200).
A critical swing from any stock melee (195) (except for Scout's, which does almost 50% less damage, and Spy's, which cannot randomly) comes just 5 damage shy of killing a full HP Soldier.
A critical rocket (270) can only be tanked by a full HP heavy, or an overhealed soldier (300).
A spy's random revolver crit is 5 damage shy (120) of instantly killing the classes he's designed to counter (Sniper and Engineer, both 125).
Sniper's quickest headshot (150) will instantly kill everything up to a Medic. A fully charged headshot shot (450) is the exact amount of health an overhealed Heavy has. Both just so happen to be his most common targets.*
A critical pipe (300) is lethal to everything except an overhealed Heavy.
*Yeah I know, random. Sniper can't crit outside of headshots on his primary. It still counts. The numbers are the way they are for a reason.
The game isn't balanced nor designed around random crits, no part of the game stops working without random crits, no class balance changes without random crits, its a dogshit design descision that benefits literally no one and there's nothing healthy about it.
Mad cuz bad.
The Fucking Ingame Commentary said:
Critical hits are one of the features that resulted from our focus on pacing. The critical hit system attempts to slightly influence the highs and lows of the game, by increasing the chance of a critical hit based upon the player's recent performance. In summary, the better you're doing, the more likely you'll continue to do well. This helps create those rare high moments, where a single player goes on a rampage and gets 3 or 4 kills in rapid succession.
Across all my playtime only wannabe tryhards kept complaining about random crits, most often when a regular attack would have splattered them anyway. "Wah i totes would have won that exchange if not for those pesky random crits". No, bitch. You had less than 30 HP.
Valve fanboys are the biggest retards on the planet I swear. Gaben could literally show up in your home, drug you and fuck your ass and the next day you'd be on the forums like "Ok but here's why that was a good thing."
Ending with a strawman. Nice. Out of curiosity, when did you start playing? 2015? 2020? This year? I'm not very familiar with the timeline of Cuckle Dane's spread of "random crits le bad i main engineer" faggotry.
