Or a little bit of both, depending on stat weight, Sam hit hard enough to make skillspeed relevant now that it increase auto-attack rate (remember 1.0 when monk auto-attack were the higher damage overall).
But yet, it all depend with the soft/hard cap, stat weight.

I'll probably gonna go with deter. Crit. and Direct-hit, because of our de/buff long enough to be reused without losing them, and i'd rather hiting hard than fast, because you know, numbers ;p
