BBot - The best bot of the world

Like most other bots, the have a magic wall "renew" (not sure if its the right word), let me explain, when you throw a m wall, it has 20 seconds of existance, you guys could make a macro to shoot an other one as soon as the first m wall ends..
That would help in wars alot and in Ots mostly..

I dont know if it is hard to do or not, but i think it would be very helpfull to have that on the bot.

Thank you for your attention
