We have four tank classes, and we want them to be roughly equal. I say "roughly" because I don't realistically Aoc Gold think with different abilities and mechanics that their survivability, dps and threat generation are going to be identical in all situations. You may struggle a little more in certain situations and other tanks may struggle more in others. As long as you don't get to the point where the group starts wishing for another class to come tank, we're probably in a good spot.
