Hello I wanna make a dark mage for PVP, which one is better in your opinion ?
or
The one with linker is to have easier exp grinding I guess
no one ? 
I need opinions
I don’t think you can PvP with your boss summon with just Sorc C1
sorc 2 is a lot better 
, and I’m so excited to know about warlock c2 and c3 
Like @tampon said the only major loss I’ve felt by taking linker1>sorc1 is in pvp performance. To keep it short and sweet, I feel both are very decent builds except that #2 brings more to the table in pve.
