I pulled my second Roy today, the first one is +atk/def, the second -atk/+def, the first is better but should I merge them to patch def bane?

His weapon gives L!Marth a bonus to each of his stats, equal to the bonus already on them and that bonus doesn't count as a buff, which makes it possible to get a max of +12 to each single stat, regardless of season etc. .
Add the L!Roy A-Skill to that, and he can get +18 to all of his stats... let's just say, that this sounds quite disgusting to have to fight against... especially if you have a L!Azura, who can easily give him those +6 to all stats and grants him one bonus field for moving...
I say don't merge, because Roy's A-Skill is so insanely valuable, there are far too many units, who could benefit from it, even if it's just for infantry
Your "reply" has nothing to do with the comment above, you replied to OP himself... oh well.
While powerful, bonus doubler comes with a heavy opportunity cost - most characters would prefer DC or a breath skill for special acceleration... the characters that don't need it are armors who benefit from special acceleration on their B slot and have DC in their weapon. Bold fighter units still want a breath for EP - the only ones to meat all criteria are thus speedy armors who can switch to special fighter and have DC in their weapons... Which leaves us with L.Tiki and Zelgius. Hardin's 28 spd isn't enough imho.
Armors can't inherit this skill.
This skill is best used on units with DC on their weapon and good mixed bulk. So, either an infantry dragon or Fjorm (or Roy himself obviously)
PS: Hardin's speed would be enough. You can stack a LOT of stats with this skill + Kaden. A +10 Hardin with those would reach 50 speed. That's why Roy's speed is way, way overkill
