I agree with many others on the basis that the animations aren't very good. However, what I disagree with, is the gun play being "bad". For one, just because you didn't like it, does not mean that it's objectively terrible, that being said, opinions are opinions, and I still respect their points. But the gun play is supposed to feel like you're pulling a real gun around, and real equipment too. That being said, I get how that could be an unwanted mechanic, but I think it adds depth to the game.
Another argument I very much disagree with is that they stole things from Rainbow Six Siege. Yes, R6S has leaning and cameras. No, R6S did not invent the use of in-game cameras or leaning. Leaning is a mechanic that has been around for a lot of games, as are in-game cameras. They stole nothing from Siege. As a matter of fact, I think that everything except for the concept of a siege-esque breach and clear type game is original. They made original gadgets, and they have original strategies, as well as the entire way you plan your attack. The only thing that seems more like Siege is the fact that you are protecting a hostage, a well disliked mode in that game, but makes for a great mode for this game.
