I cleared it (with bonus boss) recently on my fully geared tank with a healer in 230 gear, one nearly fully geared dps, and a level 56 dps who had never done it before. I even said to the group that we might fail bonus boss but was willing to give it a shot or two, then we one shot it lol, although I died at the very end to enrage. Although numerous times I've failed in groups on Sav-Rak because the healer can't keep the group up, even healers in near/full 248 gear. So it really depends on skill more than the gear tbh. I think the difficulty is fine as it is.
