The problem with the match maker is that it doesn't discriminate for groups at all. The big problem with unlimited-size groups before was that the match maker actually statistically favored placing groups against randoms because of the way it fills the teams.
I think phase 3 matchmaker does seem to place 1 group per side now if there are 2 groups but I'm not sure what happens when there are 3 or more groups present. It's possible groups size is not taken into account so 1 team may get 2x groups of 2 while the other team gets 2x groups of 4 which could lead to a 0-8 stomp. Without official word from the devs we can only guess based on observations such as seeing multiple names from a known corp on the other team when dropping in a group.
Weight class matching is a potential problem with unlimited group size so in this case total tonnage matching may be a better option. This would allow the matchmaker to match similar size groups a bit easier if unlimited size grouping was allowed. The old closed beta matchmaker that matched weights exactly seemed to be exploited by teams choosing an unusual combination of weight classes to have a near 100% chance of getting a total pug enemy team.
This could be prevented by forcing an equal number of groups per team and in the case of unusual weight class drops the matchmaker tolerance could increase over time or min/max tonnage limits could be used to allow for faster matchmaking.
The important part is matching equal size groups so each team has a similar size group for better game balance.
I think the question here is what the players really want most:
1. Do players want unlimited size groups back? The cost may be less accurate weight and Elo matching but unlimited group sizes would match up against each other.
2. Do players want accurate weight class matching? The cost may be smaller group size and less accurate Elo matching but weight class matching could probably be exact matches.
3. Do players want accurate Elo matching as we have now? The cost is small group size and less accurate weight matching as we see now.
