That is also something that might come in handy. I play with two account right now, one on my tablet and one on my cell phone.

Hopefully GREE can make something like logging in with an e-mail account or something.
I think the block reduces the damage a good chunk, haven't watched the numbers enough, but thinking like half damage.
Damage is reduced with one third, i.e. 33.33 %.
