Damn stalonka show up and activity increased. Great times to live <3
Edit: BTW stalonka I don't know what is your current financial situation, but I have 150k spared in case you are looking for investors.
Well when I had that problem some years ago I opened 7777 and 2106. Check internet, these are some useful links. Maybe you need to open ports directly from your router. I can't help more than that. Wait for someone more experienced.
As regards what? Balance? Less bugs? Content? In my opinion all classic brand is shit. There may be exceptions for files-servers that fixed many many missing things / bugs, but still devs cannot catch up with the updates.
Still there are rushes, enlightments, final secrets, weapon blockade, frost-hurricane-blazing armor, assassin gnomes e.t.c enough to keep c6 players away.
