Absolutely spot on.
I'm a "solo-builder" myself, and I have to tell you, I LOVED when they came out with the auction house and all the new enhancements with bonuses. It literally made my original character (level 50 Energy/Electric/Electric Blaster) worth playing again, and making him solo-ready was amazing as well. Sure, with a little tweaking, my rad/rad/rad defender was the bee's knees (only GM or AV I couldn't basically solo was Ghost Widow), having a blaster that could once again single-shot snipe Lt's from the safety of a window ledge was oh so much fun.
This is the type of things that I, as a "solo-builder" look for in a new game. I want to build my character to an exacting detail.. I want to have a backstory and a REASON for being there fighting crime (or DOING crimes).. and I want that flexibility to say "ok, this build is for solo, and this build is for teaming" and be able to swap them out, which CoH did really well also near the end. It's also why I'm chomping at the bit to see actually pulls the rabbit from the hat with the new game.. so far, my money's been here.
