so. i'm planning a equipment set for my 73 berserker.
seen lots of doombringer with draco and majes. which is better?
or does both has its own situational use?
as for the weapon. Gram Health is the best right?
and tateo set for the acc? i obviously cant get queen ant and other expen acc
then the rest of adena for giant codex to enchant skills?

when is the best time to enchant skill anyway?
and which skill should i prioritize first of all?
Rush impact, crushing pain and disarm?

Well it would be best to have a gram+health for pvp and a gram+focus for pve but the health weapon can work fine too since kamaels got crit rate/crit power boosted with the furious soul buff and true berserker if i recall correctly,anyway if you can afford a focus gram dont hesitate since it wont hurt to stack up crit rate.
Obviously majestic is used in case you fight stunners but overall draconic is way better if you pimp it with attribute stones+you have more pdef(doombringer is pretty squishy without Sword Shield thus extra pdef is more than welcome).For jewels,tateo set works just fine since soul barrier has a very nice cooldown so you can run around most of the time with 2k+ mdef.If you decide to use draco or dc light which is a very good option too i advise you to get a zaken.
Also get dark on your weapon and go for the dark route on your rush impact;disarm and crushing pain should be enchanted too
