And as for merging and doing a vote change afterwards, I don't think that's a viable option at all. The 80% requirement to pass a vote would simply lead to a large amount of people being stuck on settings they don't want to play on.
Most of your post just confirmed my previous comments. Every new uni being some random unicorn means no uni's can really be merged without some kind of sacrifice. I pointed this out over a year ago, but that comment fell on deaf ears as far as GF goes. There is no. X merges to Y list that gives EVERYONE what they want. The goal is to merge unis the least painful way to do that is to go with my most recent suggetion, give players as many choices as possible 3-4 options could easily afford a player multiple speeds and sizes. At the end of the day, for most of us we have to decide whats more important to us though, speed or size...
To the quote above, I think its silly to reverse alot of the voting thats already happened, because some forum warriors said so, BEFORE they even commit to picking a uni. If I get on here and voice that I want virgo to be 1x, but then I pick a diff uni because my buddy did... i'm just 'voted' for a uni I don't even play in. Thats why I saw worry about changing settings AFTER the merge. I understand your concern, in that you want to make sure you go to a uni with settings you like, not go to a uni with X settings just to have them changed right after (this will happen anyway though because votes just happen periodically anyway). IF 80% of your uni disagrees with your preference its just tough cookies. This kinda circles back to whats most important, size or speed... atleast speed can be changed if you rally the playerbase, no one gets to VOTE on being equal sized to ur opponents lol.
Ultimately, its like you and I have said, there are ALOT of things to consider when matching uni's for merge, and because of that there isn't a make everyone happy solution.. which is why so many people use the phrase whats best for the most people. We kinda have to just accept that the few are going to get screwed here one way or another, regardless of who that few ends up being, its really for the greater good of the community.
