I agree with @Sully to an extent, with the addition of strong T items you do lose a bit of the raw gun still that separated players before, but overall I think the plugin brought some good additions to the server and I definitely more players enjoying the new plugin than not.
One thing i'd suggest for the random teleporter would be to have a global time-based cool down on it , i.e 30+ seconds give or take, opposed to the 3 global uses nerf. I think part of the problem surrounding the random teleporter is that early in the round there are so many people in groups it's really damn hard to discern who teleported with who, giving the T's a huge advantage. With a timer-based cooldown instead of a total-use cooldown, there won't be nearly as much confusion at the start of the rounds and it will give the detectives time to prove players allowing people to KOS t's who switch with a proven inno.
