It wasn't that hard at the beginning of ShB because most people who played are familiar with basic mechanics and their class. However, lately a lot of Players (who assumingly only know how to buy a skip potion from the mogstore) leveled up and have major issues with this fight. I ended up there several times with Trial roulette (probably because it is in such a high demand right now).
And as a good mentor I try to be, I explain the fight over and over and over again to all the six sprouts, who are there with me. I set up marks, I tell them to stand in puddles, to stack together with stack marker, to tank the adds and to not face Titania in the raid for a killing spree.
So... besides the whole DPS issue and the enrage timer.... I've seen it all... Tanks not caring for adds, stack makers with only four people, always at least one puddle where noone is standing.... And I'm patient. Most of the time we are doing this for 40 minutes straight with NO progress whatsoever... I don't mind a wipe or two or three. But if people don't adjust - especially after I'm telling them what went wrong and how to avoid this and you are still on P2 and can't get past the adds... Please, don't blame me if at some point I vote abandon.

Looking for a PF group to help you out would be much easier at this point. I don't think that Titania needs adjustments - I just think that the skip-potion-community finally realizes that mechanics are something you should start to do.
