No.
32 Seconds is MORE than enough invis / near god-mode time. Not to mention you get an insane melee dmg buff while invisible.
If you can't find a little wall to hide behind for less than a second to press the "2" key again, then it's your issue, not the frame's.
PS - The only thing I would like "buffed" on Loki is to make his 1 relevant. It's a light reflection and supposed to "distract" the enemy, but for some reason, it both doesn't even scale and is pretty much OHK...by bullets...while everyone and everything can walk right through it (Logic / 10).
