Well....if you're still punishing arrows on reaction then good on you, maybe main Geiger then? It's still possible but more prone to baiting now, as a smart Jaina will zone you out then bait a super when you'll end up too far to punish her in recovery and just eat knee-fireball to the face, or DP, or block punish or whatever. Of course if Jaina is just derp spamming arrows like an idiot you can just position yourself properly, stroll across and ruin her day.
In short as I see it, the arrow game when he has super is much more fair now, in my experience. You can punish a badly spaced/timed super now because of its recovery frames, but if he does his job well he can punish your arrows. It's not like before where he literally had no risk whatsoever.
And as for getting aggressive with the DP its all about understanding how that economy works. If you hit someone with it, you're even on damage, but they are grounded and you have room to weave your rain of terror. If you play Jaina well you should absolutely shred health bars with block damage when you get a knockdown and room to breathe, and you use the tapestry to set up the next DP and keep the train going. Plus, since the DP can't kill you, you aren't really losing out. Play it well and they are close to death when you are, except that now you suddenly became so much more dangerous because you have unlimited DP's.
The only time the DP is really counterproductive is when up against high health opponents such as rook and midori, but they do so much damage per hit if played properly that the difference between getting killed in 2 hits by rook and dying to one damage is almost immaterial.
At this point, no, Geiger no longer has Jaina's number. If you're getting slayed by Geigers, then do what the guys on the discord told me to do when I first started moaning about her.....weave better arrows.
A well played Jaina is almost impossible to approach...
