There should be a option on the gods page to buy a exp boost. It would give you a certain % more exp for what ever time you buy it for. Like lets say you get 200 exp off of a person, with a exp boost you could get up to 30% more exp from them or anyone you win against for lets say 20 minutes. You could buy a 5% boost for 10 favor points, a 15% boost for 20 favor points, a 25% boost for 35 favor points, and finally a 30% boost for 50 favor points. The reason im putting the favor point prices high is so people with alot of favor points wont abuse it. I know someone is going to find something bad about the idea, but nothing in the world is perfect. Edit: I am talking about fights only, the exp boost would not affect the exp you get from boss's.
I see where you're coming from believe it or not. A 5% is pointless as you get that from berserk boosts... 5% is a weak boost anyway. Anything past that though and now you're talking. It's not a 10 as this can get abused big time(sorry to say your prices are not high) It's a 7 from me. EDIT!!!!!Another way this will get abused is use that boost PLUS the stamina boosts..sorry vote just changed to a 1.
I know, people could always up there stamina when attacking, but that makes there stamina go by faster. Id rather be able to get extra exp and only use 1 stamina per attack.
