Just make TT1 equivalent to auto-distribution, TT2 %50 current capability and TT3 equal to the current TT1's Shield Distribution.
Hmm if they dont remove the auto distribute, i think this is an excellent idea. So instead of hitting (going by default settings) right arrow to distribute shields to your right shield facing, it will do it automatically. However, the effect will not be any more than it would be when hitting "right arrow" shield facing.
I dont think the higher tiers should do it anything like it currently is though. Right now its Reverse Shield Polarity
Im going to post that suggestion in the other topic.
