First off, the Regressia Knight sucks, outright. It's slow, weak, and has about zero usefulness in a group. It can heal, but it has such slow mana regen it's very rarely handy.
This brings me to my next point, I don't want to use this crappy class, let me use the Hazordhu Orc. The ability to select which cross-subscription starter class you can use would be very nice.
