I hate the new ones.. I still remember the old ones and it makes it harder for me to find buffs (and to know at a glance which spell gems are what).
But I just live with it. Sigh.
If they gave me an option in game, I would use the old ones. I have 6 or 7 installs of EQ spread around various systems and I don't think I'd be dealing with manually updating them every patch.
I never understood why they changed the spell icons.
