I'm going to guess it's from sheer ability bloat.
I myself am guilty of this somewhat. I really don't use E4E as much as I should, mostly because I haven't had it for so long and perhaps partly because it's yet more clipping to play around. And well, when you have 4 hotbars of ability, it's hard to not neglect something now and then.
But I hope SE doesn't use that as an excuse to axe Benison come the expansion, I love that ability...
