cbble isn’t REALLY even, but it’s not bad. But then I tend to join the losing team cuz I like the challenge, so if it’s unbalanced, it doesn’t bother me much.
Don’t forgot to add assault (original and upc) and militia to the list of unbalanced maps.
Oilrig isn’t too bad if you don’t suck. 
I think the part that makes it hard for the cts is just getting the VIP into the helicopter cuz there’s so many places the t’s can pick you off from.
I still like this rotation:
