at it's core, the game is extremely fun and f2w. The default character is my main and I find alot of success with her. However, the server can be laggy at time (more than occasionally). If you are a good fps player, you can pretty much roll over the enemy team with mechanics alone.
Another bad thing about this game is the ballance. there is too much damage but not enough mobility. I can tell that the dev is trying to make the game feels like overwatch. but in overwatch characters are much more agile so 2 headshot kills are fine. but in this game even the fastest character is not fast enough to escape the aim assist. there isn't much counter play to a sniper 1shoting people across the map.
to sum up, this is a free to win game with every character strong enough to be viable and a good time killer but can be frustrating when you get deeper into the game
