I liked listening to all the specifics on certain builds, powers, etc. However, I pretty much went my own way too for certain things depending on my own play style.
I did notice when certain things were squishy or strong (i.e., MM ninjas being very squishy, but good at single target attacks). But, I still tried to enjoy the various facets of the game. though I didn't so much get into the warshade/peacemaker, nor the arachnos archetypes. I tried them out though, but not for me. I didn't do too many of the tanks either, but I did play them.
I'm sure when we get back into game and even "when" the CoX 1.5 option comes around, there will be plenty of info out there along with testers of various things. I'm just eager to get back to heroing or villainry at this point.
