I needn't remind you guys that a creator has the most farming of all the classes if you intend to use it as your main character. Yes this is the way it was intended however in iro botting is allowed (by this i am not promoting this act). It's just that other classes has gotten much more advantage from this server mods compared to the several restrictions on the creator class (vs iro).
So all in all a few potions as a reward for BG and imo more so WoE would not unbalance the game if done properly, and it would likely lure more Creators to be actively present in WoE/BG not as a result of exploitation but rather enjoyment.
