I'm sure this has been thought or or should have. Firstly I like the idea of perks, it gives more meaning to warring and winning. U should in deed get something for being good. But what happens when u were once good and aren't anymore. If that clan was once a lvl 10 crew (perk lvl) but have struggled since then, they are still receiving the perks and have no reason to care.
Suggesting perks can be taken away just as they can be earned.
Example: if winning gets u 50xp lossing should drop some xp or failing an attack should drop something.
a clan should be persuaded to remain good and strong and not be allowed to receive perks they no longer deserve. I can see in the future a dead clan passed on with ppl that have nvr warred yet th7s are racking up donations by receiving and giving lvl 6 wizards when they had nothing to do with the part of the clan that worked for it. Who may now all be gone.
If a perk lvl is depleted of xp let's have that perk lvl drop back into the previous lvl and force the team to maintain.
That ends my suggestions for the day. Thank u for reading
