Beast Tamer Character Creation Event: 1/14 – 3/9

This doesn't really add any difficult challenge to bossing other than to waste your time. If it's a set number of hits to make the enemy buff disappear, classes with low hits per second are at a disadvantage against classes with high hits per second.

It at least makes it impossible for anyone to solo it. A Weapon Cancel pops up, well now your Zero can't do anything. So you have to bring someone in with you to deal with it. So your F/P whittles down some HP and now the Weapon Cancel disappears and is immediately replaced with a Magic Cancel. Now the F/P is mostly useless until that Zero pulls down some more HP from the monster. And it keeps alternating throughout the fight.

Maybe it doesn't add any difficult challenge, but at the very least it stops the ridiculousness of playing solo in an MMORPG.
