LvL penalty between pty members.

[StormWalker]

The penalty is now 5 levels, it would help a lot to level new friends to the CP, to make it more attractive and fun. It takes a long time to get them to be in the level range without penalty in the party.

Or implement some kind of event about 2 times a year with removal of penalties per level, that helps a lot for friends who are new to the game or who are picking it up again.
