Bosses should 'consume' projectiles
Or a better idea: Outline of the target, visible through all particle effects.
It would just be nice if they outlined the creatures/bosses so you could make them out better. They already do that subtly with the players.
That might help for some effects but not the most problematic ones like the burning from Guardians. The problems with the birds and other similar effects is that they scale too much with the bosses, most bosses are not fat enough to hide the birds in their body.
Other effects are not even on an enemy like Time Warp. Sometimes it is just the zoom such as the fight with the Statue of Dwayna.
I think gw2 effects are amazing, but they really need be toned down. don’t want to lose the effects entirely just tone them down. Even better, like some people have already suggested in other posts, having a slider like for gamma for eg: would be an ideal solution. That way, in big battles u could turn them down and turn them up when the party is smaller or playing solo.
