Honestly. I do struggle to find full games in Classic. Always 3vs3...
I had the same issues in Hardcore.
They should totally do mode consolidation. Classic and Hardcore together. Votable in game
Maybe that could bring in whoever is playing Classic and whoever was playing Hardcore to create a bigger pool. Also everyone gets their mode and no playlist is punished.
With DLC now free Classic will hopefully get a little life injected back into it.
Ever since Classic mode was created, it was the ONLY mode I played. It didn't have all the ridiculous annoying stuff to rage over... kickbacks (quickboom, etc), power plays, M9 RoF etc. Unfortunately in the tail end of my UC3 career, hahaha, it was sometimes impossible to find matches. Somtimes it would take up to 20 minutes to find a match, and if I did find a match, it wouldn't be a full 5v5.
Hopefully you are right with the DLC maps being free, Classic will get some more life into it. I actually may take a break from the TLOU MP and come back to UC3 for a second.
