Hi,
Thot I posted this yesterday but cant find it so will try again:

Can I get some feedbacK on what is an easily learned UI interface for a Mage that will be usable for other classes? I am new to EQ (relatively speaking, hub has played for years) and the basic ui is not very user friendly. (Too big and not enuff info on exp % and pet, etc.)
I am a little leary about messing in the SOE files, but installing maps went ok. I dont want something I have to patch every time sony does a patch, too because I am not real whiz at computer program fixes.
I am running my game on a Presario AMD athalon 64 512RAM, Win XP pro sp2, Nvidia gforce 4 graphics. I do get a lot of lag in PoK most times and some of the zones if lots of toons on. So I need somthing that wont slow me down any further.
Any ideas and guidance here would be appreciated.
Thanks!
Ophee
