Moaning about Afterburner aside, I'm genuinely impressed by how most of the other things being complained about (read: offered actual feedback on) are universally in regards to GFX and aesthetics. (Though, I don't personally see the point in Infiltration even with the slot investment, but that's another story; I'm still trying to play around with it on the beta and there's genuinely not a lot that can be done to give it 'oomph' without overpowering other travel powers, I think. That, and something mentioned earlier in the thread about making a pass at Stealth are why I'm leaving it alone for now.)
To be honest, I can see the argument for there needing to be a 2nd look at Travel Power animations and FX - if not in this Issue, then the next.
Because not only is there that known issue with Hover and Fly fighting for animations, the big concern about fusing the Concealment pool powers is that Invisibility's practically-transparent FX were supplanted by Stealth's more ghostly-but-still-tangible FX.
And on top of those two introduced with the changes in this beta, there's also the fact that Teleport still lacks a Min FX option in lieu of the big pop of light, as has been requested in the last Issue when Teleportation was reworked entirely.
What sucks about this situation is that all of these GFX options are valid and desirable. There are people who love this Magneto hover flight, there are people who prefer Stealth's ghostly transparency over the complete invisibility, and there are still plenty of other people (and even other characters owned by the same people) where the converse options would make more sense.
But with combining the Flight toggles, or literally fusing the Concealment powers, the number of power GFX options has decreased at the moment, and that is a concern in such an old game that lives and breathes on the amount of customization options it has.
