So, they modified Iron Tower... you can't skip Anoki anymore (the hardest fight in there for new groups). I tried going in on my fresh 80 guardian with some fresh 80's in T1's and khitai blues. It was impossible.
Our setup:
1 Guardian
1 DT
1 PoM
1 Necro
1 HoX
1 Ranger
Fairly decent setup, but it's impossible to get the girls down in time after they appear. Maybe with a demo it would've been possible (AoE bursts in beginning) but even still we had like 1 girl at full health. My suggestion: People usually just skip Anoki. Now that they made it so it's impossible to skip her (a barricade appears), they should lower the HP of the girls drastically for new players.
UNCHAINED IronTower...is a TOTALLY different matter... you should have Vistrix come down and blast us all at once then have Anoki dopplegangers instead of the girls, or something similarily insane. But this isn't Unchained, it's Iron Tower a good dungeon for new people. Anyhow, my two cents.
