I was thinking more for the Acid/ESG VS Thor's hammer thing... No weapon should outrange another weapon by too much. In the OP2 case, 2 is already quite something.
Since lasers get to range 8, Then, with thor's having over 2 range difference, it could never catch up with a laser (think laser lynx vs thor lynx). The laser can usually run away in some directions, avoiding tight corners, whilst attacking the thor lynx. The thor lynx doesn't really have any tactics to kill that laser, unless the laser owner somehow gets that laser in the thor's firing range.
By lucky hit, I was thinking about player luck. Again, for the tactic above, hit and run.
In current OP2, you can use Acids, but most effectively ESGs in lynx fights against Thors' Hammers. You just fire 2 squares away from the thor lynxes, in the direction they're heading, and they will get at least a bit of damage, whilst the Acids/ESGs remain untouched. That way, you only need mistakes or terrain to effectively take out the nasty ranged weapons. But having the same rage makes it a little easier to catch up. Thor's Hammers actually loose against acids and ESGs.
