There were very few different icons for EQOA buffs and you were never really sure which buffs you had until you went to your character screen and watched the text scroll by.
When you died, they went away. And when you were buffed, you couldn’t voluntarily remove the buff like WoW. Sometimes this would be a problem. For example, the ranger +15 health tick would interrupt any chance of a main healer’s crit.
Buffs were as crucial, if not more, than gear. A tank with avatar, the trans-pill, a druid’s AC buff, cleric’s HP and resists buffs, along with bard/enchanter buffs pretty much made them super-toons. With all these buffs along with diseases and plagues from enemies, it could take up the top 2 inches of your display, making them slightly annoying.
There was a point early in Frontiers where there was no minimum level to get these buffs. I remember being level 25 or so and having 3-4k HP while everyone else my level had 1k.
