|Proposing an inbuilt check to the defence lines so that only players +-2 or 3 levels of the person who joined first, will be allowed to pair up.|
This check can last for 1-2 minutes after which players from any CL can join that line.
The level tolerance and duration of the check can be set by the clan's leader/deputy/warlord.
Or every clan can have a hard limit fixed by admins (Which would probably be annoying for everyone).
The idea is to prevent lines with high level gaps from forming accidentally (Like when a level 20 and a level 12 pressed join simultaneously before page refreshed).
Necessary or unnecessary? :)
