Just remember that most conditions and some boons also have a visual effect, as mentioned. The edges of the screen changes, and usually the character will have some graphical indication around them relating to the condition/boon (purple clouds for confusion, black smoke type stuff for blind, etc). They also tend to shout out something relating to the condition/boon, such as "I can't see!" or "Can't walk right!" or "I can't remember my orders!" (this one seems to be the Charr line for Confusion). Once you know the sort of things certain lines of speech and certain colours of effects relate to, you don't need to look at the boons/conditions bar so much. That said, I'm fairly sure the lines of speech vary with the character's race, so each race means remembering a new set of declarations and their associations.
