Warmane Character Planner

My idea is to have a section on warmane entirely dedicated to character planning. The section should be a demo which allow us to change gear, gems, weapons, spec and see the related stats change of our hero. This will help players to develop their character stats and enhance ingame performance. Obviously the planner must be related to every single expansion, because stats/gear works differently. Moreover this demo will help players testing their new specs and experiments, such in pvp such in pve. It is an extremely efficent tool for find the right stats balance. In my opinion a character planner will add something more to this gorgeous developed community. It would be a remakable thing.
Few years ago there was a site called Chardev.org that had this project running. I don't know if you had the chance to use it, but it managed a lot of work for me. Personally i spent a lot of time with papers to trace my stats change since it went offline. Id be glad to have such a tool on warmane.

I hope ive explained my idea a little bit. What do you think warmane guys?

There's gotta be a lot of simulators online for newer and older expansions, but for wotlk I use Rawr 2.3.22, works great, I don't see why should this be up on the site.
It'd be a pain to implement if you want anything other than a stat calculator...
