Some players may find the current Ion Cannon naming convention confusing (the cannon kills all ships of a lower mark, so not including ships of equal mark). The change would make the current Ion Cannon Mark II, which kills Mark I ships, be Mark I, and Ion Cannon Mark III, which kills Mark I and II ships, be Mark II.
Thoughts?
Personally, I'm for it. I find myself double checking the description for the cannon sometimes for peace of mind to make sure it's not killing my ships because it'll keep shooting even if I don't have any ships that can be insta-killed in the system. I think having a Mark I version of the cannon will make things more clear, too, since with the current convention, a Mark I version would be little more than a fancy sniper turret, which isn't all that special at all.
