WL used to be a really really good class but nowadays they are just meh.
When i used to play bRO,my friend used to be a monster with his WL... He taught me how to avoid PW,Diamond Dust,Warg Strike,and other skills just using ICE WALL.
but nowadays WL HP is too low for all this burst damage comming from rangers,suras(Always),RK,SC,RG's,Gene.
WL is the kind of class that is better for PVP than WoE (same as kagerou,ranger,Gene),i mean... What a WL can do in woe scenario? They just spam comet comet comet comet and if u compare,what a WL can do in a pvp scenario?
As far as i know a PVP WL can drain the entire screen SP (maybe just 1~10 players know how to do it),Disable a lot of skills,hitlock targets using wizard skills and a lot of more things !
Thats why u will never see a good WL playing WoE (probably not in pvp too since the good WL's left the game),woe is just spam of skills with restrictions.
********* Yes,ranger is bad for woe in my opinion,every low hp class is (if they lost Sac,bye bye)
Sorry for the big reply
I do believe Warlocks are more suited on WoE rather than PvP since there's more room for teamwork.
They can do CL spam for ~35k-40k per hit (WoE Set) and ~55k-60k per hit (non WoE Set).... with the right set/gears that is.
Also, Telekinesis + SE can deal around ~35k-45k per hit (2 hits at once) (WoE Set) and ~65k-70k per hit (2 hit at once) (non WoE Set) plus it's a 5x5 Area of Damage spell.... again, with the right gears.
As I mentioned before, it has its pros and cons so it's up to if you enjoy playing the class or not.
