This....is the best idea on these forums since...well a lot of great ideas but this one...this...
This...could really save a lot of ships which are too weak and Muse doesn't seem to get around to fixing them.
One question tho...if the buff adds armor then shouldn't hull buffs be based off armor levels? Some of the vessels have insane hull hp but poor armor. Squid, Spire, Goldfish...maybe Mobula would benefit more from this based off armor which this would be needed the most. Galleons + Junkers would suffer some while Pyras would come in about the middle. In fact, I doubt the buff time would change much for Pyra.
The idea for transferring this to guns and engines Is good too. But I'd like to add an idea for how this could transfer to the balloon. Basically you have the balloon buff speed based on weight. Heavier vessels require more lift...hence more buffing. So lighter vessels would get a boost to buff speed on balloons.
The only major thing that bugs me is that the heavy ships need some improvements and a lot of these would benefit light. While the light vessels are in dire need of improvements. The heavies would need a touch to balance, which isn't hard. Pyra needs some turning back and galleon...just needs heavy weapons to be scary again.
