Even though I'm not a big fan of pvp, I'm spamming the feast and frontlines just to play smn in pvp which is so damn fun. It's like a neverending almost 100% uptime cycle of dreadwyrm trance -> summon bahamut, I can't even begin to express how awesome that feels, not to mention the fluidity. The way pvp smn plays I believe is what comes closest to what the SMN playerbase has been demanding.

I'd say just keep the pvp core, 45s CD aetherflow and summon bahamut after 1 DWT stack. Then get rid of ruin and ruin ii and make ruin iii the new mobile goto spell and ruin IV the DWT ruin. Add in all the pertinent OGCDs and procs and we are set...

Pretty sure nobody would miss their McDonald's toys...?
