The answer to this debate is, there is no answer.
If we leave it as it is, it is too hard for most newbies to learn.
==> Loss of community on the long-term
If we make it more fair ( ie: involves less diversity and possibilities) as Teeth suggested, newbies will want to join, but most people will not see the point of this mod and will play native/quit altogether
==> Loss of community+ gain of community
If we make it more diverse, it will expand the differences, thus leading to no pop. growth.
==>Loss on the long term
As Leshma truthfully said, this mod is old. Is is bound to go down and die eventually. The game is old, therefore the community will not grow, as players simply will not buy the game.
I actually don't believe we can get new players, so let the vets have their fun, and let the new players have their tough time. If they are not determined enough to play this game, they don't deserve to play it (bam.)
Let the mod have its peace. Take advantage of the fun while you can. Its far from perfect, but game balance is correct, community still pretty stable and its still real fun to play if you keep an unbiased view. People will be whining about stuff, that's how it goes.
We can't have everything.
