I have one critique on the clip you showed, but I will say that I think Nova Warp needs a buff in PvP. Its too slow in general, both in terms of closing gaps with opponents, and the charge time. Its dreadfully slow if you aren't blinking, and even the blink barely has any range. Then if you manage to close the gap, you'll typically be gunned down after your first burst, if not sooner. I agree the the cast should be the full AoE. The one problem with your clip - it looks like you got melee'd (or at least I think it was a melee) right before casting the super. I'm talking like, withing a second of the cast. You're health was already down to ~60% before actually entering the super, which is part of why you died (although given how fast he killed you, I think its fair to say you likely would've been killed even at full health). It seems like the damage resistance is much lower than a faster super like Arc Staff.
