It's a similar case in Neverwinter Online now that I've finished the main quest story and am sitting on level 60. What's left to do other than raise professions? Well, I CAN'T run the skirmishes I missed (all of them) without making an alt, which I think is bad design. I can still go do the dungeons I missed though which is good, and I can still do foundry stuff though I prefer to make quests as the incentive to play them (especially solo) is a bit ... meh. That leaves the "epic" level dungeons. The catch? All the epic level stuff is behind a gear check wall. I'm currently around 4000 points short there to be eligible to run the last dungeon (Castle Never, which has no normal mode. Epic only) which means it's hamster wheel time if I want to reach there.
Guild activities are always fun though!
Now would I rather grind gear score in NWO or do the living story (currently Cut-throat Politics) stuff in GW2? It all comes down to the one that gives me the most sense of progression and fun. In this case neither since I stumbled back into Age of Conan this week with my supposedly "test" character on the wrong (pvp) server. Why? Because things are still new to me and there are some really pretty sights and music, despite people trying to gank me. ^_~
