Can't find the antag roll overhaul thread so i'm posting this about rolling antag

[Moon Jesus]

I feel like I get antag in streaks, and then I don't get it for like a whole month. 

Example: Last night I got nuke ops. I could have bet my entire life savings that I would get antag next round. Guess what? Got vamp. I'm about 90% positive that next round I declare ready on I will get antag. Probably 1-2 more times after that, and then not get it for a solid month or two, depending on how many times I play in that timeframe. What gives?

I'm literally avoiding playing right now during low-pop hours because I don't want to be 3 crew changeling.
