It's going to be a power upgrade because you can just slow roll for the first few turns and bank a bunch of shields.
On turns where nothing is happening, you throw another shield on there/regen one.
If you have higher PS, you see where your opponent places his ships, and then place your Gonk ship in the best possible place to run for as long as possible.
A scum Boba with Gonk can slow ride/run for a few turns and start accruing shields. Then when he loses his shields he can fly off and start regenerating them.
There is down time during games and this is something people on the forums seem to forget. Jumpmasters and Firesprays will be able to just 4 straight and boost and then start regenerating next turn.
