No dont change it. A lot of ppl have been asking for that middle ground between easy content and difficult content (savage). This for me is there. Im just an average player, dont do savage, normally play a healer and was able to beat it on my 4th try (ilevel 236) all in different groups in DF.
It hasnt been 1 week yet since release... Give it time, gear up some more. If community sees that after 3-4 weeks a lot of ppl are having difficulty then maybe ask for it.
For me it is fine as it is.
