Because raid setups don't care about lore. They are based on class power and utility. There's almost no one raiding on blm or smn right now because these classes are simple not worth it compared to rdm. Blm will never get enough dps to cover for rdm's battle res without becoming completely broken, so i wouldn't expect any buffs honestly. Smn is useless and just needs total rebalance but that's another thing for another topic.
But the problem is still on hand, you either switch to rdm to play high end content or accept the fact that you make your static's life worse by refusing to do so.
I'm raiding savage content as blm actually. Every time i see when people are dying and healers don't have time to res them instantly I know its my fault to not chose the right class over the one i like to play. They don't force me to switch into rdm, but i know im dragging them down with my decision to play this class. Not the best feeling honestly.
