Ill echo what a few other people have said about the Omega raids(non-savage) not being hard. They progress from fewest mechanics in V1 to most in V4, but regardless of how "complex" any of the fights are none of them are punishing enough that one player goofing up will tank the group. Even 1 bum healer/tank can be survived in any of them as long as their counterpart is on point. A DPS whos not fully up to speed just means it takes longer to finish. So dont let the "raid" name scare you away - from these or the alliance raids that come in future patches. Try 'em when you have time, see if you enjoy, and keep having fun.
