The problem about Roze is not that it's hard. The problem is that it's in fact very easy except for one single jump part, which is just annoying. I can tell you what happens if someone really picks it.I think the map is equally hard starting from jump part to the ending slowdown. So it's like half of the whole combo.
I'm disappointed that this map is in nomod bracket. It would fit either freemod OR a hr pick in ko stage.
As to other maps, I still find some being easier than the rest, significantly. But maybe it's just player's preference. Overally I think the pool is quite ok.
Jump Around and this TOTAL OBJECTION are pretty boring, but it's again taste.
