Hello,
It's not that I don't want to play your game, or hate your Mystic Knight class. Far from it. I love the concepts behind both of them. I do want to be in your game, but I can't seem to find a class that is acceptable to my senses without stepping on any previously submitted characters. I would play a duskblade or even a spellthief, but I can't bring myself to play a "martial" character when your Mystic Knight is staring at me; begging to be played lol.
It seems like it was meant to be a primary melee character that dabbles in arcane magic and debuffs. It is my personal opinion (and could very easily be wrong, as I have been known to be before

), that the class is underpowered as a melee character. Yes, at higher levels it catches up but it would be surviving the lower levels that could prove difficult.
