That was the entire plan. To make it hard for the class who pretty much has been dominating ToH. Why do most people go on a sniper? Because it's easy mode.
A lot of these mobs were made to make it difficult for snipers, yet still doable while being a trial for mage classes, etc too.
A bunch of snipers got 45-50 points.
A lot didn't. It did what it was supposed to do. Not everyone is supposed to get through and perfect. Just a certain percentage, otherwise why not just make the wings a quest that everyone can easily do instead of a trial? :X
