Twelvesky2 this is an important announcement I got from the site, just take a minute to have a look !

We have finally decided that the only rule for joining Sky Clan will be: It will be eligible which the Clan with the highest clan points only

In power over time We've realized that the current system that's in place will ultimately create an imbalance.It seems that as more players continue to level up to Adept, more will be inclined to join the Sky Clan. The imbalance may not be felt directly right now.

But bear in mind that since everyone in Sky Clan will be A1 and above, this will only create problems in future. If too many Adepts from the Dragon, Snake and Tiger clans were to join the Sky Clan, the latter will inevitably remain in top position.
Since the declaration is only available for 12 hours on Saturdays,

it will ultimately create long term chaos in Wars, Holy Stone Battles, and open maps such as Prajna Mountains.

Since Sky Clan was available we've seen these issues getting repeated over time ever . We're also aware that many of you are concerned about the power shift leaning towards Sky Clan. We do not favor any specific clan, and neither are we trying to prevent any from being the most powerful. Make no mistake,

this new system is not meant to diminish the importance of the Sky Clan. More importantly though, is the balance of power. And how this balance is correctly maintained over time.

Maybe it could give some useful information, and thanks for time ! here is the link about 12sky  : 12sky gold and twelvesky2 powerleveling !
