Add Mutagen to Arena!
Another thing you can do in Arena is to let us see what the persons hero line up looks like before entering battle, same as Hero Trials! its really annoying to go into battle and see the guy is over powered and then end battle etc. It takes time and is annoying.
The Guild Boss is useless and so is the Guild Quests, Really dont see the point in spending all that time to get Guild credits and then get 60 Souls? Whats the point?
Also that little chest where you invite people from fb is useless, remove it!
And how can you put up a trade like yesterday(09/05/16) 4000gems for 88 Talent refresh beats. Its shit! i already have like a 100 of those in my vault i cant use. Cause those talents always refresh to the lowest available talent eg. 1/8 1/5 or whatever! and then 200 gems to "Light One Up" F2P guys are not gonna waste gems like that, its USELESS!
And lastly update the algorithm for Dice rolls, its always the same! and any idiot can see its rigged.
thats just my 2 cents!
I have plenty more suggestions!
