Lycanthropy is no fun and a real deterrence to gameplay. If you don’t think so, try pure Faction 500 without potions.
A better idea would be to have it JUMBLE the other team! Now that would be FUN.
It would be a race to match it before the other player. And it does not dramatically change the tide of game. If you are winning or losing, that doesn’t change but if you jumble the other team, you might gain a slight advantage.
