OWL was honestly the biggest spit in the face to the community. The forums never agree on anything, but the one thing literally 100% of the community agreed on was that OW was in no way, shape, or form ready to be introduced into the eSports scene. Despite no one wanting an Overwatch eSports and the roster being completely and totally fucked (which it still is), they debuted while reworking arguably the biggest hero in the game, and it came out looking like shit. It's just two different teams with the same exact hero comp and strat going toe-to-toe. Then the devs start making their balancing changes around what the pros want instead of what their actual playerbase needs. The game ends up being a nightmare match of counter-picks where the only heroes you can play are either meta heroes or just direct counters to the most OP player on the enemy team.
Not to mention the attempts at "balance" (which were way too fucking little, too late) have all fallen squarely flat on their faces. The 2-2-2 role queue was a certfied shit-show. They locked maps people wanted to play for no reason, decentivizing people to play comp if their prefered maps weren't in rotation. They locked four different heroes a week for fuck-all reason, decentivizing players to play comp if their prefered heroes weren't in rotation. They released heroes into comp without taking into consideration the community's feedback from the PTR, which, depending on how good/bad they were in comp, they'd either make so bad that you couldn't play them, or they'd overpower them so much that they'd be the meta; just countless amounts of totally amateur errors spanning four years that this "seasoned and professional" gaming studio made.
It's sad too, because this game had so much potential, but these incompetent and lazy ass devs just completely ruined it. The game has been an unbalanced and broken mess since day one and the developers just don't seem to give a shit, only now because their Titanic of a title is sinking when it hit the iceberg of reality, the reality that their name doesn't carry any weight anymore and the hype from Overwatch it had at first is completely fucking dead and no one really gives a shit about it as much as they did before; only now do they want to steer this game in the direction they should have before, but it's far too fucking late, which they realized, which is why they're making a sequel which isn't really a sequel and is just a much-needed patch with a $60-$70 price tag on it.
And people will buy it.
