GO back to ALL the previous quests, fix those spelling mistakes, make the 'story' between quests in a chain a little more clear, add in 'missing' mobs so that optionals can be finished.
Nothing else.
Kinda tired of all the quests that are older than a year or so, that have been neglected from day one with missing beholders, wights, glaring spelling errors, confusing, if not completely misleading, stories in a chain, etc.
I'm sure people could give many, MANY examples of the above things, some of which I would fail to remember.
Also would like you to go throw that switch to make GH epic... and maybe titan too(Wouldn't you like to sell that pack again?)
