I was originally thinking about this in terms of PvE to avoid duplication of effort, but the PvP comments are valid, even if it's a bit of a cheap way to distract an opponent =)
The most compelling reason for not displaying them is that we have no means of dispelling or purging the effects from ourselves or others, and adding such abilities would not fit the playstyle of this game very well. In the current situation, it doesn't really matter (in PvP) beyond the protection auras. In a large battle of the scale we used to see, there was enough damage of all kinds flying around that only Invuln would have made a difference, and that prevented you from participating anyway except as a distraction =)
So yeah, this probably wouldn't be overly beneficial to the current game.
