Thanks for the replies guys!
For the timings, the T's arrive at A site in 8-9 seconds while the CT's in 5-6 and for B site the CT's are in the CT entrance in 10 seconds while the T's are in the B main entrance in the same time, so I guess I have to make the CT's reach B faster. I guess I'll use both of your ideas and move both T and CT spawn more in the middle and move B site to the right. Thanks!
