So I haven't played in a long time and I came online only to find the action point system has totally changed and now I'm lost. I used to have a pretty good mix of light spellpower and healing, but now it seems I'm really being pushed to specialize in one particular tree and I'm not sure what's best.

I generally solo with my cleric though I'll occasionally join a party for raids/party-based adventures. He's not all that high level, just 11th. He always used a long sword before with the 'follower of the sovereign host' enhancement but now that seems to be gone. Is there any way that I can still use the long sword I bought? Or is it basically just junk now and will have to be replaced with another weapon? I see that warpriest has a tree that enhances certain weapons based on the deity you follow but I don't see anywhere where it lets you choose what that deity is and I can't see anything that gives long sword proficiency.

Can someone give me some advice?
