Idk, I can queue up for Orbonne and it pops in about 20 mins, same time it takes to pop a Q for LotA. I don't know what the problem is. None of the Alliance Raids are dead, just bc one or two player get ARR often :P You can't force plyers to do anything, they will just not do it anymore. Acting as if it's impossible for people to clear the raids is unrealistic.
And I doubt that Alliance raids are the place for people to learn mechanics and how their class works. 30% of the force can be dead or have abysmal DPS and you can still clear.
