on the plus side, it means that there has been optimization already done on the engine.
on the minus side, it means that most of the optimization that will ever get done has probably already been done.
I like how you think its so easy, 3 towns, 15 channels each, 45 channels each with their own gold spammers. You think its easy to track megaphone chat in 45 channels at one time lol ?
Its not even that bad anyways, stop going to klaipeda/orsha/feidiman 1-5 unless you need buffs from some random or want to card battle. The other channels are free from spam and lag.
