I think the difficulty of Omega 1.0 Savage is perfectly fine. Was in my first group today, we wiped about 15 times total and still did not finish the boss. However in one night we learned a lot, had fun, and got the boss down to 20% before he enraged (people died a ton so our dps suffered).

I'm sure the later bosses in the raid will be harder, and they should be. but having tried 1.0 so far I think its fine where it is as the intro fight.
