As my alts approach lvl 50 (I took the scenic route), I'm concerned that I won't have any interest in playing after cap because there is no way to "grow" anymore. Yes, I could raid for gear (I'm a soloer), or do it for the story, but so far no solo content has been added since release.
Legacy is a good start - it gives me another set of XP to go for, but it's not yet rewarding enough to pursue for its own sake. Other MMOs have item leveling, which keeps me engaged. A way to level our skills or companions would be awesome.
For the devs: Because I know at some point the level cap will be raised, I feel like I'm wasting XP by doing quests after I'm capped out. If I have other incentives to keep questing after 50, such as knowing that it gives XP to legacy, gear, skills, or companions, then I won't care so much about the cap. And that will keep me playing and paying.
Anyone else agree or have similar ideas? I know - do the group content, but unfortunately I can't due to RL.
