I am interested in it, but with the loot distribution as is, it's a waste of my limited game time. I prefer to go where I know I can advance my character a little bit instead of going where I may have a slim chance of possibly advancing it more. I'd love to get into VW, WoE, and Neo-Nyzul if they didn't feel like they'd be a gigantic waste of time. I don't mind challenging or time consuming, but I do mind being unrewarded for my conquest of the challenge and spending of my time.
I don't expect a reward for helping friends or newbies, but I expect some form of advancement when seriously participating in endgame content. Each fight should be a step forward in some way. Why do you think guilds and linkshells came up with DKP? It's not just to sort loot, but to give members a feeling of progression while doing largely unrewarding content. Now, for better or worse, SE has taken DKP out of the equation so they need to fill that void. Maybe the OP's solution isn't perfect. Maybe it isn't even the best solution. There's obviously never going to be a perfect one, especially from SE. It's still far better than letting pure dumb luck be the sole arbiter of advancement.
I'm not really sure what there is that's appealing for you to do in the game once you "finish" with Abyssea content. Perhaps SE will bring out more casual-oriented content in the future to appeal to your demographic.
What's going to be appealing to you once you get lucky with the drops you want?
