He's a good player but he lacks communicating skills. Communication is very important in a clan.
This. And I don't think he will improve his English (call it an instinct).
Anyway, the application is not dropped, let's wait for 2-3 more votes, but bear in mind that he still has 2 negative votes, that should be taken into consideration. I still stand behind what I said: he may be skilled, but he's not a trustworthy player.
