Please no.
There is already so little interaction and synergy left in combat between players, so having to get rid of one of the last "remnant" of these kind of abilities would be a bad idea. (Can't really view things like raids wide spells as interesting "interactions")
Doing this, as said up, would be the equivalent of opening the pandora's box, after that who knows what we'll have to get rid of.
As of today, during fights it already feels like we are "playing at the same time as others" rather than "playing with others" with the lack of interaction, so the more we go this way, the less it's gonna be enjoyable (for me at least)
I can stand some idiots, easy to avoid them or even play with friends, but a stale and boring gameplay, not so much.
