I personally don't like the idea of an aoe lift power as a substitute for dimention shift. (For a few reasons) Mainly an aoe lift power will still give you a pretty hefty alpha strike, even if you could put enough recharge into the power to keep everyone in the air all the time. Secondly your going to miss sometimes, and then you'll get two volleys of alpha, sure you might say but an aoe hold also misses. This is true, but an aoe hold stops the second volley (those who did fly and are now getting up onto their feet). Thirdly, I don't want to see some of the unique qualities of gravity being replaced by similar ones. Essentially making gravity two bit powersets- lift and hold.
As for dimention shift, I think it is perfectly fine as is in PVE. It's a panic button, and a segregator. However, I do feel that dimention shift's true potential is yet to be tapped by the dev team in PvP. They've set the precedence by tweaking powers and how they work in the two settings (pvp and pve). Powers which are useless in PvE have been given some attention in PvP. Brawl is the easiest example to put forth, but there are many others. These intangible powers, should do 2 things, the first is return phase shifters to reality -and- prevent them from returning into phase. If someone is caught in phase shift, by an intangible power they'll have to suffer the dregs of reality for the length of the dimention shift/blackhole. The other thing Dshift should do is *drum roll* drop toggles. Now this may seem very powerfull, and yes it is. But consider this. When the toggles drop, you the controller still can't do anything to the target. They are essentially phased. So essentially it becomes a race between the target and the controller to see who can get their powers in fastest after the intangibility falls. In this sense shift would work completly differently from other toggle drops, it would drop toggles fairly reliably, but on the other hand it dosn't mean the shifted can't recover.
My 2 cents
