Best Sothe?

I have an unmerged +HP -def Sothe and I find that his speed is often just a couple ticks short of scoring a double, but it's tricky. The HP boon is surprisingly effective because I can tank a single hit (brave weapon counts as two) from pretty much anything, and he's really hard to double without QR/vengeful, but then glimmer (or I could switch to moonbow) should finish them before the second riposte. If I give up the bulk I'll have a hard time initiating on anything that can hit back unless I switch out L&D (in which case my speed goes down...don't want to give him swift sparrow unless I will merge him) or can somehow get desperation going.

I feel like I can KO most things in two hits (maybe sometimes short 1atk, but your merges should deal with that no problem), especially if the special activates, so I don't feel a need for more attack, but go with your experience on this one.

Sothe doesn't really 'need' an attack boon, compared to a speed boon, since he has 50 attack already with Peshkatz equipped, but his speed is only 33 at neutral (looking at an unmerged Sothe here).

More speed means more doubles, which is fairly important.

SPD is Sothe's best boon. His atk is high enough as it is that a few extra points doesn't help as much as the speed does.
