Two things are ruining the game. First is the killing of pvp. Now, with all perks like can't take damage, immune to every thing, silencing from the beginning, resurrection, and so forth a pvp match takes way too long. Use to a person could jump on, play a couple of games in a couple of minutes. Now unless you have 30 minutes it's not worth playing.
Second is you are ruining events. They are not worth the grind. Before you could grind hard and at least get a good rune. Now to get any thing worth a little effort you have to drop money. I don't mind spending a little but I'm not dropping 20 for every event.
Greed kills all mobile games.
