It really sucks that the LIVE ARENA mode is simply not fun and forces you to be restrained for a long time.
If you lose, there is no reward, and the recent update has made it easier to be matched with stronger opponents and the chance of losing is higher than before.
It's a shitty content that will only increase the amount of wasted and unenjoyable time.
I have been playing this game for several years now and every now and then I get fed up with the game. I used to pay for it in the beginning, but now I find it a ridiculous game to spend money on more often than not.
