Same here... we have 16 members, 14 of which are opted in, and 10 gold towers. That's ridiculous
So basically the only way we'll win a defence is if the attacking guild is catastrophically inept. Not very likely when you're ranked 9th overall.
Since GREE apparently is focusing on adding new game modes and refusing to fix literally any functional bug (UI bugs don't count when they don't affect UX in the slightest), I don't expect this to be addressed. But @DSKenshirou_X if you could add this to the mountain of bugs reports submitted to the QA team, I'd appreciate it.
