Thunder M3 seems less usefull than twins M2; in the picture below there is my comparison.

me too; where is the button "sell thunder kit and refund crystals"?

After introduction of laser scope shaft became useless and inefeffective in comparison with other long and mid range weapons; it was my favourite weapon but now I use a different one; the acceleration of Shaft’s scope is irrelevant IMO. Shaft users are quickly decreased, isn't it dear staff?? This is the only reason of shaft "rebalance" but your idea will be useless and vain, you can bet. Suggestion: next upgrade add the button "sell shaft", it will be more usefull then acceleration of Shaft’s scope.

As a shaft user in standing tactics, I am not happy with this update and might switch to other weapon now. In my opinion: FAIL UPDATE
