Its counter productive if you keep rerolling and then say you beat the game on hard.
What you should do is play on hard on your first play through and try beat the game. This way you don't feel cheating on yourself by restarting over and over again to make thing right.
On my first playthrough, I mistakenly made a mage that use a bow but I enjoy it so far. The urge to restart was strong but I just keep playing.
Defeat my first boss with that dex-mage at level 7 on normal and I nearly die.. 19 health left xD
