1st question, what's really the purpose of morale in frontline and wd.

2nd question, is it a good idea to pentameld 110 pvp gear if Gil is not an issue, will that add something for me, and if so should I focus in melding det and crit for maximizing dmg or should I do vit for survival. I main mnk in pvp btw. I'm rank 40 and almost to 41, so I really close to rank 44 and have a full set 110 hawk set.
