I'm going to run the assumption it's a 12v12 game as that game size should be released before the game is officially released.
1 Assault per lance, with a maximum of 2 per team.
4 Heavy maximum per team
unrestricted medium per team
2 Light maximum per lance. with a maximum of 4
it's a little restrictive, yes, but it still leaves the game open enough where I don't think it will cause excessive queue times (unless you run purely assault mechs).
Combined with some lobby system that allows players to switch lances and the ability to queue by weight class instead of by mech, and choosing mechs in the lobby, could increase the level of strategy used in the game and keep the general flow MUCH better.
Granted medium mechs may need restriction later on, I feel having this kind of class balance could keep the flow of gameplay away from herpaderp alpha striking assaults and instead push more DPS-oriented gameplay, and encourage players to form subgroups instead of just zerging around the map.
If it's too extreme, it could even be some form of "Structured Matchmaking" alongside the existing, for players that would prefer this kind of setup instead of all assaults all day.
