I do.
The big thing I do miss is the old RSD on USA, there were constant substantial tests and more passive RP. It was less breaches and raids.
I also miss the novelty of many of these things, I remember playing for the first time and going on tests, where you actually didn't know what each one did. The primary server side change that I miss is the less frequent, larger and stronger breaches. While breaches are fun, they got repetitive and now they feel overdone. (I thought the opposite when I was in E-11, being bored out of my mind standing and waiting for something to happen)
And the map changes, Old HCZ, and Old IA office are the big two that stand out to me.
All of this could very well be rose tinted glasses. But roleplay just felt better then.
