No. This change would actually encourage that style of play.

You have ships that physically can't escape collision under certain circumstances, particularly the VSD. So it would actually encourage even more abuse of the ramming rules to annihilate tough ships.If you expect to lose an unshielded, overload pulse'd Assault Frigate to an Avenger ISD, you can ram it and cause 6 hull points of damage for next to nothing. Same with a Motti Raider. A bone stock CR90B is only 39 points for 4 hull, after doing even one point of damage to a Gladiator you could ram Demolisher to death in a single ram under your rule.

Personally, the ability to ET and ram twice is the most egregious. That's just dumb.

I have always liked the idea that the big ships just push the smaller ones out of the way, or same sized ships do the same by sliding on the table along the tool pushing the smaller or same sized ship out of the way. and the damage on a ship equal to the other ships size class.

there are 100s of videos of ships hitting each other and never does a smaller ship stop a bigger one from moving.
