But if RNG subbing COR instead of WAR or SAM that's way too much WS dmg lose when COR can still /WAR + getting QD charges. Not to mention if they're using WF, they can't boost WF dmg before QD(when COR can probably boost every WF if it's 6 charges), so it's not exactly the same.
I'm just saying if SE thinks RNG falls behind COR from damage standpoint then a RNG should obviously be subbing COR to gain access to its QD abilities. If a RNG/WAR can keep ahead of a COR/SAM with increased QD charges then there is no reason for SE to be worried about RNG.
A RNG/COR, assuming he's in the COR party will get Tactician's, Miser's, and can run his own mini-nerfed Chaos buff. He'll get QD damage that he can get close to COR levels by using 127 dmg bullet (unless COR has Omphalos), which is almost 30 points higher than Orichalcum Bullet. He can WF for bit less than COR due to no AF3 +2 boots effect but better AGI gear. Then he can far outhit a COR with Last Stand due to better AGI gear options, better RATT options, better bullet options. He can also out ranged TP a COR with velocity shot, true shot, better bullets, better RATT.
THis is only assuming 3 or 4 QD charges make that big a difference to damage that it outweighs a RNG subbing SAM or WAR, which I doubt it would. Realistically it only matters at the beginning of the fight unless SE changes timers.
Then again VW is just stupid so why would SE care that much.
