That tank will prolly be my next project, once I get my two Justice Defenders slotted with IOs (retrofitting), and a couple of my other 40somethings hit 50.
I have a 39 Shields/Fire Tank that has been plenty of fun. I know I like WP, and now I know I like Fire Melee so odds on the wee tank are pretty good.
The biggest problem I have is the planned build absolutely does not figure in for exemping below... well 38. My attack chain is horrible! So when I start playing it again I will have to make a leveling up/exemp build.
