I just picked up the game on the GoG summer sale. I'm leveling an Arcanist and am level 13. I haven't picked a secondary mastery yet. I'm using a pretty simple PRM build.
I could use some suggestions about what would be a compatible secondary mastery. I really like lightning, stun, debuff, and aether. I like ranged and aoe, but ranged isn't a necessary. Retribution and defensive auras are always fun too.
I'm trying to forward look towards ultimate and would like some suggestions on what other classes (masteries) people think might work well with that. I've been thinking shaman, nightblade, soldier as options in roughly that order.
