Maybe? I dunno. As someone who plays a lot of "I just dive people k" champs, 700 range isn't that big of a deal to me unless they're on the stronger zoning side. With a good zoning comp, I can see trying to dive 700 range to be rough but in most disorganized situations, not really sure how well she'll fare there.
I dunno. Triforce second rarely feels right and I'm not really sure if she has the kit to chain Sheen procs with impunity. But, at the same time, it does "feel" like TF is something she would want to have, though part of me just thinks that is due to TF's current power level.
Edit: I'm still thinking BT first to make the most out of her W's tAD scaling + the natural ASPD she gets (even Rank 1's 50% is pretty much comparable to most mid-level steroids anyway) might be ideal. Dunno. I'll have to put time in her to get a better idea for that.
