Mercer has destroyed interest in the guild war.
Mercer is too unbalanced. This hero completely destroyed the interest in the guild war. Now all enemies die in 1-2 turns.
New maps after the update brought freshness, but also passed without effort with the help of an unbalanced Mercer. This hero broke the balance of the game too much.
You should have done it in the warrior class, melees need a hero like that, but gun teams don't.
The game is getting more and more boring... Or make sure that only melee heroes can go to some guild war islands.
And in challenge Mercer kills everything like a nuclear weapon, it's a pity that this hero is not a warrior.
