Improvement in which aspect?
I do find IR ranks to have amazing determination to pull off what they are currently doing. That clan is pulling surprising numbers.
Same for Sup, it's not easy for both clans to be in a rivalry for so long, there is always ranks burning out, but both sides keep going.
I do not see improvement in Foe, aren't they always doing the same? Out of all the clans they have least action. They are dominant at weekends and in clanwars but who is there for them to help them prove it anymore?
In my opinion, I've been in foe when they were doing good, I have not seen that clan to stick their neck out even once to take a chance, they fight only when they think there is 110% chance to win.
I don't know much about other clans, one spike in pull for MF cant really be used to determine anything, the clan is simply built around having fun in wilderness and pking together, not for competitive play. Being the best is not always the most fun, stressful stuff considering how serious bsns rs clanning is.
