Help with a Spines/WP build
You'd be better off building on the defense already present in the build, and that's typed defenses, not positional.
Comrade Smersh, KGB Special Section 8 50 Inv/Fire, Fire/Rad, BS/WP, SD/SS, AR/EM
Other 50s: Plant/Thorn, Bots/Traps, DB/SR, MA/Regen, Rad/Dark - All on Virtue.

Been trying to squeeze as much defense out of this character as possible, wanted to do a respec for a long time, just didn't get around to it. Not sure what else I can do...but I got my melee defense up to about 32%.
