Level 75 now, approaching the end of Hell difficulty, Act 2. According to the experience chart [1] I should stay in Act 2 until level 80, but the xp penalty of playing through Act 3 instead is minor. I should probably just advance the story, so I can get what I came for and get out of here.
I thought the immunes would be a big deal, but you just have to work around them instead of trying to steamroller through everything. Some of the lesser bosses are a much bigger pain than the actual Act level bosses, but sometimes you don't have to even fight them (teleport in, get quest item, teleport or portal out).
As long as I'm still making progress, so to speak, I can keep going. Really, though, this grinding is all quite pointless. I just want to get to the mountain top for the sake of getting there, I'm not actually enjoying the view any more.
