If only I could edit my post
I spent an hour or three doing IAs and came across some issues/bugs.
End bosses had 3k health and that seemed fine but their damage was too much. Yulelogon did Wild Explosive growth, an aoe attack, that did 466 damage when my health is 950. I used my faerie Seer to attack him and he never chased after it but stayed put.Bosses with Aoe attacks seem to do them to players that are around 25 m from them even while not in combat.The damage of other bosses might be too big but I did manage to kill them rather easily without dying. In IAs currently on live I find it near impossible to kill some bosses unless I use Fury of the Acended but on these bosses it failed to work and the damage taken was the same with it on.
There were a few issues with the Winter's Chill quests: in Storm legion and Rimetaloned Gustriders they did too little damage even with their special attacks. Both Rimetaloned Gustriders and Frosted Windlasher spawns were too quick when they died sometimes within seconds of death.
Winter wassail: there seems to be too many winterglory spawns and too few Nutleaf. Also when it's hard to find herbs it's made worse when the npc demands a herb and decriments what you have collected. Not fun when soloing.
Rudy's Roundup while cute suffers from a low respawn rate. One attempt the corgis were spread far away and on another only a few spawned to strt with. Nine seems to high for a simgle player considering they have to travel far 9 times and the (five minute) buff fell off while doing this too. A reduction or a speed buff would be nice.
In Little helpers, the buff still says Rudy's Way in the tooltip also the buff would only last what seemed a random number of charges ranging from 1-6.
Dance for Snow would be much better, in my opinion, if we had an NPC to dance beside rather just where we stand once accepting the quest.
I don't know how the snow patches affect anyone but I dip from 30fps to around 20fps when I do that quest on my own with 8 patches.
I'd agree with the above poster that a few unique snowflakes is rather low considering that items cost in the hundreds to buy. Don't be a Fae Yule scrooge. :p
Oh, can we get an achivment for the IAs or maybe just a couple since from what I see they all seem to be PvP achievents atm.
I didn't come across an invasion event while doing the IAs for a few hours. Have they been disabled by mistake or was I very unlucky?
