Hello,
I would say MCS is functionnal for several use cases and might fall short for a couple of them. Answering clearly to such a question is pretty tough: that really depends on what you're trying to achieve, which probes you want to target, the complexity of profiles you want to deploy, the volume you have to address... Could you share a little bit more details with us?
MCS is now the path to go anyway, and even it will evolve, it will probably not change totally for a while. You can invest time on it but requirements should be wisely reviewed before. CA Services could give you a hand if needed!
