Just tried to play on Hardcore and for me it's the worse mod I've played on in times.
Don't like the gameplay there at all, please keep it to jaymod.
People say that silent has 2 servers, always full.
Same goes for jaymod, we have 4 servers of which 3 are always populated.
If you change jay4 to silent, you just turn the problem around.
Then jaymod is always full and silent has 1 server with few population.
Besides that, jay4 is not the most populated server, but most of the times there are enough players to play without bots.
