I personally disagree. Locking 370 behind savage is perfectly reasonable. It's the hardest content in the game, and as such the rewards for completing it should be well worth it. If they gave you the best gear outside of the content, then there would be no incentive to complete it other than personal satisfaction.
On the bright side, they'll have a catch up patch in 4.3 that'll allow those who want to be max level without raiding to catch up. I don't think there is anything wrong with giving those that put in the time and effort some time to enjoy their gear before others can catch up. It's not like the gap is that large of a difference. If it was say, 40 item levels, then sure I might see an argument.
Secondly, @ OP. I don't know how much dps you do, but most statics don't worry to much about dps if you can do enough to kill the boss and not mess up mechanics. I think plenty of groups would rather a player that can survive and do poor dps, over a player that dies to every major mechanic to greed their numbers. Of course a player that can do great dps and survive would be a perfect world but you don't achieve that status until you get several upgrades later from farming after you clear. Numbers while important to almost everyone doesn't mean to much to players until after you have content on farm status. The clears come first, the padding comes later. If you can do the content without dying, you'll naturally do better dps over time. Low dps only stresses groups out if you're hitting enrage, but most groups can overcome enrage naturally if nobody on the team dies. Survivability and reliability over maximizing damage. In addition, don't feel discouraged because another player is doing more damage than you are because of gear, if anything, look at it like it's less competition for rolling on gear if something you desire drops. The better the gear your teammates are, the quicker things die, the more chances you have at rolling on gear you otherwise might have had competition for assuming they already have it.
