I am really surprised none of the builds have Teleport Foe in them. Soloing, it was a HUGE benefit to break up some of the arc missions, stripping away lts and minions in final battles and helping to break it up well. I actually like Heroic's design, though I was thinking I would just not take Pulse Rifle Burst, take everything 1 step earlier, and then TP Foe when you hit the empty spot (I think it will occur around lvl 10).
I have had some end issues at 20 when really hammering the heals, a tactics, and such so think Stamina would be a good addition. I would miss Howling Twilight, at least conceptually; I have only ever used it once and would guess that if things were so horrible that I needed to use an AOE rez, I myself would likely be nearly without END anyways....I guess I would get far more use out of the other powers...
Does Group Fly work well? I had Group TP cause it seemed cool, but generally seems to blow...
