[Gameplay] Tryndamere can Ult while in a GA respawn

It's possible, if you have a GA while playing Trydamere, to use both at the same time. If you miss your ult timing and die with a GA, it will still consume your ult. When you respawn from GA, your ult will be on CD and you will not have any of the benefits (30hp immortality for another second or two, or the added Fury).

Obvious work-around answer is to not be bad and to ult before your GA procs, but I don't believe it's intended that you can ult while in a GA respawn.
