LeRoy's speed is great already, and with +spd, Human Virtue, and Bonus Doubler, it can get into overkill range easily. I'd prefer +res because he has good mixed bulk and DC and it makes him even better at fighting dragons. I would keep both copies until IS announces the additional effect on his Legendary blessing (I think they said April).
L!Roy IV Question
I managed to get L! Roy twice. One is +Spd, the other is +Res, and they both are -HP. What should I do with the spare: fodder for Bonus Doubler (and who would benefit from it if I choose this option) or merge to patch up the flaw?
I'm also hearing really interesting cases for keeping either +Spd or +Res. If merging is justified, which asset should I stick with?
With 50 Spd after bonus Doubler (as his ceiling) he can't double anyone with 46 spd. 46-47 is a fairly common amount of speed before buffs let alone with buffs. I think people are being too quick to dismiss +Spd. I'm not saying it's the way to go, I'm currently deciding as well. Just food for thought.
