especially because we have the GREAT possibility of reincarnation which allows "to play ALL classes" without changing, but from the beginning, so you can learn about the new class....!
partially true.
An inc will never be at the same level of the main toon, unless someone begins to live inside allods and play all his toons 23/7 :/
If I'm tired of my class and I've a geared toon with fable/fable 56 glyphs, upgraded lv60 equip...honestly I won't exp an incarnation to use it for endgame contents. I exp it for my pleasure, for golds, for have more chances to do AoD or goblinball or other things like this.
But it's VERY hard, imo, to put on the same level a main -geared- toon and an incarnation. Now more then before, given that there is all the lv60 to upgrade.
