No help???
Not worth levelling?
Kashhrek is a good tank for players still very much early in the game, until you will outgrow him by reason that you have better tanks to replace him. He was supposed to be played again by veteran and experienced players who used Kashhrek as tank when his costume was released, giving him the health boost similar to how Heimdall does to his allies. I guess, IMHO, I expected too much on costume Kashhrek than what he can actually deliver as tank.
i’ve maxed kashhrek & i guess if you don’t max his costume he’ll still be a grade c vs costumed grade b+?
