Like GS/BR, weaken ABing dramatically during the first 1000 turns.

1) This will really diminish the likelyhood of oop wars, without making them totally useless.
2) It will hurt suiciders in the first few days.

Hm

But we only weakened the end bit of BR/GS, ie their killing speed....

The changes to gs/br were enough of a deterrent for at least the first 500 turns, maybe it could be extended further 1500, but i think hurting ABs (maybe returning them to the low -> high -> low returns for the first 1500 turns)
