Fair move
EOP's slump is not like that of FOE at their lowest.
It is a genuine surprise that they are still open, their leadership is the weakest it's ever been and their members have no ambition to further the clan.
While it isn't "nice" to leave your clan, he is playing this game to have fun, and quite frankly, it is UNFAIR TO EOPS MEMBERS for the clan to still be open, and for their leaders to ask their members to commit their time playing such a shit game for such a shit clan.
The fact that he would talk to his friend (presumably, i mean he's ranked afterall) suggests that the clan, regardless of slump, is not somewhere you'd like to be.
I hope you get accepted and have a great time in FOE.
