I cannot stress enough that you should NOT buy this game.
The actual gameplay is pretty good, for a console MOBA it functions mechanically quite well, but you'll never see it. When you very rarely do get a workable game going, it in no way makes up for how completely and utterly broken everything else is.
The matchmaking process takes on average between 10 and 20 minutes for a game to start (I have no idea where they get the 'average wait time' that's displayed while searching for matches, but it's completely wrong). When you're finally paired with 9 other people, 9 times out of 10 someone will drop during the character selection process which often causes the game to hang on that screen, unable to proceed into the match. If you quit out at this point to try again you'll be locked out of matchmaking.
If you do manage to get a game started, there will often be some lag. Sometimes it will be manageable and only cause a constant annoying stuttering until people start inevitable disconnecting/quitting, but most times it will be a crippling slideshow. Even if you're lucky enough to get a game without lag, without a doubt you'll have at least one person disconnect during a game (not kicked, just plain be dropped from the game), running the risk of causing the game to hang in an unrecoverable state of trying to resync until you're forced to quit, at which point you'll once again be locked out of matchmaking. This is only if you don't have someone outright ragequit during a game, often causing a cascade of everyone else quitting. Now you're back to waiting another 15+ minutes for a game once your lockout clears.
The game has been plagued with game breaking problems since it launched, and none of them have been acknowledged or addressed. They have however gone ahead and created/released an entire separate game mode, and close to 10 characters to buy along with an entire map re-skin. Lovely.
In addition to this, apparently Xbox versions have been plagued with a glitch where users will be forced into 'gold mode', essentially a trial version with no dlc, no updates, and can only play with other users that are in gold mode as well.
Don't waste your money on this, and don't support developers that care much more about milking money out of you than providing a product they can be proud of.
