Looking forward to this.
When BulletCatcher came around I thought: "Clever thinking, well executed", took my countermeasures and moved on. With MoxieBot I thought: "I want to be able to do this too". But I like to win, and not to 'not loose', so I won't let my movement dictate where to shoot. Passive bulletshielding, making use of the accidental shadows created by the gun, is the way to go for me. Although my first attempts at even creating the environment to start develop it horribly failed with version 3.3 and some more till 3.10.
I can't and won't dictate others what they should and should not use. I can only decide for myself, and conform myself to the rules of the community. But don't forget that a too strict 'ruleset' could stop innovation, making the rumble a tweak-competition.
