A simple fix for the random weight matched drops for small-group/lone-wolf matches:
1) Allow no more than 1 pre-made group on each team.
A more complicated fix could better solve balance issues for small-group/lone-wolf matches:
1) Allow no more than 1 pre-made group on each team.
2) Place an equal number of pre-made groups on each team (0 or 1).
3) When possible* match the pre-made group size by number of players.
*If exact match is not possible +/-1 player matching could be used. A pre-made group of 3 could face another pre-made group of 2, 3 or 4 while a pre-made group of 4 would only face a pre-made group of 4 or 3.
Even with the simple fix this would force an end to sync-drop groups on the same team. This would balance the game for both the small group players and the lone-wolf (pug) players. This could also have the side effect of forcing some 4+4 sync-drop groups back into the 8vs8 pre-made drops.
If something is not done soon to fix the sync-drop problems, the number of players will drop to the point that a group of 8 can drop against anyone just like in closed beta. Phase 3 ELO matchmaking will not work if there are too few players to make it work.
This isn't a threat to quit if changes aren't made but it should be very clear that players are unhappy with the sync-drop 4+4 teams still being allowed continue.
