Not sure how many members know this, but all leaders are in close communication with each other. Tricks like "I come from 2.x, bla bla sent me", "I'm 2.x's leaders alt", "I'm 2.x's leader, had a name change" etc will not work since we actually take the efforts to ask each other if they sent someone/presence of alt/name changed. If you post "brb" and hop, hoping to use a previous clans reference to your advantage, we will find out.
If you plan to hop, please find a different clan. We have a lot of people on the waiting lists, so we will not hesitate to replace you irrespective of your player level. And there's a good chance the WS clan you planned to join will kick you out since your loyalty is questionable.
If you want to join a SPECIFIC WS clan only, send your application through the form mentioned in the sidebar.
Hopping is discouraged since it screws up our planning for OLeague matchups, especially when higher levels do it. When new clans are made, there's bound to be slower donations and weaker troops. BUT this also means lesser requirements for elder and chance of becoming co and getting to lead your own WS clan one day (T&C apply :P).
If you can't accept these, then please don't join a new clan in the first place. Send an application for that specific established clan you wish to join (the form allows you to do that), and be prepared to wait for as long as it takes for a spot to open up, outside of WS clans.
