I think that the difficulty is fine right now, if not pretty good, at least when it comes to normal content, not too interested in extreme content and still on the fence about giving savage a try once it drops.

My only gripe would be that it feels like some mechanics go off a little too fast in the normal raids, like bombs/Lariat in AAC3 and Clone cleaves/alternating lasers in AAC4. Having an extra second/half a second to move would go a long way because the mechs are very much "MOVE IMMEDIATELY OR GET CLIPPED IF YOU HAVE BAD PING", especially if you don't process where to go almost as soon as the boss telegraphs their attack.
