Even in high rate realms such as Icecrown. I currently have a level 80 Druid and I want a little more variety when I play, but I've personally started to feel as though I'd only need to create and level one alt (Paladin). Any more than that just seems to burn me out regardless of what private realm (high rate or x1) I am playing on?
Too add on to this question, does anyone else feel differently than I do?
