I'm not sold on suites yet. They were good in 4th, but the essence reduction, while nice, isn't going to sell my sammie on them.
If you can't combine suites, or add to them, then they're pretty "meh" in my opinion.
I get that they're special, and I get that they're custom, but the idea of spending 125k for a 95k suite to shave off a few essence points, and not be able to add anything else (bio OR chrome) is not a route I'll take with most of my characters.
Though, for an infiltration specialist, or face, it might be okay. I COULD see it for a decker, but your average sam is going to look at these and go, "Can't ever upgrade? No thanks, Chummer."
