I'm definitely thinking Ranger will be my "Do it all" class. Level in PvE, WvW, do SPvP, Dungeons, and just over-all explore and achievement hunt with him. Wiggly Boop will still be by my side for the long run. It's just too much fun finding random weapons on the ground.
Engy will be my level at a leisure pace in whatever strikes my mood, or level with friends character. I thought that pistol/pistol would be my weapons of choice, but I really fell in love with Pistol/Shield, which I DID NOT expect to happen at all. Rifle was still cool, but kinda meh overall imo.
I still have some interest in my elementalist, but I have a feeling she will be WvW centric leveling. At that point I can only handle so much of the PvE aspect. Definitely playing mostly for the awesome human female outfit. She's so cute in the brightly colored skirt and frilly shirt.
I have lost interest for the warrior. I have also no interest in necro or thief. Guardian will probably be a change of pace class just when I need something to do for an hour here and there. Or Mesmer. I'll have to try a mesmer in SPvP just to learn how to counter one. No better way to learn a counter than to play the class itself first hand.
So yeah, Revised list.
1. Ranger
2. Engy
3. Elementalist
4. Guard / Mesmer
