I would recommend VV over Sea daughter easily. Regain is only 2/tic, but you get a huge STR boost and another 10% double attack. Pet tp moves are wondeful useful, but the recast timer is much more of a limitation than tp gain. Also, the slow effect is wretched to our damage. We already cannot stack much haste on pets, adding slow hurts their main source of damage: normal melee.
The lack of razed ruins for damage dealing is... devastating. You and your pet both do much much more damage w/ rr atma. I've no idea what Tsukino is trying to say w/ that quote:
I just assume he's trolling in a 1/2 coherent way..."Why doesn't my RR atma effect my pets?"
RR boosts bst perhaps more than other jobs. it boosts both main and pet damage. Crit hits seem to boost pet pdif more than 1.0 (which is how much it boosts players, it seems closer to 2.0 for pets). The crit hit rate from RR atma on pet alone will boost most pets up to around 60% crit hit rate. The 30% boost in crit damage stacks w/ the 8% from crit attack bonus that pretty much all 75+ pets have (I haven't confirmed for merle, don't think merle gets it as mnk)
