Cannon bonus on siege units IMPLEMENTED

I think we should nerf bonus of cannons and catapults on siege units so that most siege land units and ships can at least survive without getting one shot killed

Also galleon using cannon shot twice makes its basic attack useless, so i think cannon shot should at least have 1 turn cooldown (plus bonus damage lowered to not kill another siege ship with 1 hit)

You're right, but I wonder if we shouldn't go a step further.
Remove catapult bonus vs regular siege (too many mobile units with this category - all those packed ones).
Change all cannons bonuses vs siege to bonus vs armored siege.
Accuracy vs setup machines should still be perfect, as they have 0 speed, so that shouldn't be a problem.

I am also thinking about trebuchet - no bonuses is too weak and 100% accuracy vs packed wagon-like machines.
Maybe assigning another category is a must.
