Casters, rogues......or more specifically just in general......if u have a low amount of hitpoints please be aware that many monsters in this game cleave.......stay back or attack from behind.
I see way to many low hitpoint builds thinking they are safe because they don't have aggro and just standing there like a pinata. If u are in the path of such foes...they will hit...and probably kill you.
Yes stuff like diplomacy works to shed a monsters aggro but they are still going to hit u if ur in the way. Also if u do not have heavy fort by the time your in GH....don't even go into front line fighting. Moderate fort is not even good enough considering how hard these monsters hit if u have low hitpoints.
Clerics and healing Bards have a small mana pool when such players are in a group, and I have seen so many FvS that don't heal or only heal themselves...or heal very inefficiently because they think they have plenty of SP and are out before they know it.
I don't know about other healers.....but if u are this type of player....I WILL NOT heal you.
Thank You
