If we are attacked by another player and the defender win's they should also gain exp ?  If the attacker attacks more than once the % of exp decreases?

I don't understand the second part of the question, but you only gain or lose experience when you initiate the attack

That doesn't make any sense, if someone attacks us and loses we should gain some experience. if we lose we end up in the hosp for a while don't we?

It makes sense because that's too passive. If someone doesn't play for a month and a bunch of people attack them and lose, they'll end up leveling up when they're not even actively doing anything.

what are the chances of that? what if you don't log in for 3 days then you don't earn any experience? would that make it fair?

No, I think it's fine as is. To earn EXP you have to initiate an action

yes but you should also be awarded for someone else initiating an action and defending it because you have them out train'd, if someone loses thats because they were out train'd no ones fault but there own but the person out training them should be award'd even if its only 10 exp every little bit helps ...What about a battle ladder rank system

both argument make sense to me..

but i dont want to get attacked and earn exp...lol there are so many ways to get exp already...

or else follow dyablo suggestion but remove any exp from gymming...make more sense but we will get the same result at the end..

so i see no point changing the game as it is...

To be honest, I don't mind whether or not you gain exp from being attacked and successfully defending. Its balanced enough that the other person loses experience, I think.

But, I do like the idea of removing EXP from hitting up the gym. Makes no sense to me... At this time, people who do not want to level up really don't have a choice. Practically everything you do will force you to level up.

That's kind of the point: to prevent level-squatters
