I'll recommend not getting Royal Battlemage, it's not a good class but overall, your list seems good.
However, I suggest getting Nulgath items in between sagas/storylines. There are easy Nulgath gear like Crimson Plate of Nulgath, Death Scythe of Nulgath, Claw of Nulgath which has 2 upgradable versions which need Rank 10 Evil and Good respectively, etc. Having Nulgath gear (for me) equipped motivates you to farm and complete the storylines, and makes you feel good about your character. That's one factor that makes AQW fun at the moment. Sad to say, it's an epic dress-up game/MMORPG. Having good gear while killing mobs is a must!
Btw, I can suggest a certain armor combination. It may fit your taste or not. Get Rank 6 Vampire at /safiria and buy the Vampire Emissary armor, pair it up with the Fiend Cloak of Nulgath. The cloak costs 500,000 gold and it's from Nulgath's shop himself, you just need to cell-hop to m22 on /citadel and go inside the portal. It'll take you to /tercessuinotlim. Cell-hop to Nulgath and buy the cape. The weapon is your choice, but if you want suggestions, just drop me a PM. Hope this helps.
