Is there a particular power or effect? Things can get tweaked over time, just not likely this week.
I'm sure folks will agree that is is great we are getting new content and powersets. With that will come some wrinkles to be ironed out and differences of opinion.
I did play the Seismic Blast set to about level 30 so far. Seems pretty great and the large animations seemed to be very brief. I can see on a large target with a league some annoyance.. but I've been dealing with that in leagues for some time (auras, area powers, etc), so kinda par for the course. Definitely something to consider though.
Unrelated question:
Is it too soon to request a unicorn or giant flamingo innertube? Even better as unlocks (don't throw stuff, I like earning items, sue me).
