With I6/ED you have decisions to make with defenses. For me I decided to go for max resistance, and that meant biting the bullet and getting the Fighting Pool. I dropped Perma Haste which isn't possible any more as well as Focused Accuracy which hogged too much END to be viable any more.
With this build I get close to the cap with Lethal/Smashing (about 89.7%), and and around 26.1% Cold/Fire/Toxic & 27.3% Energy/Negative. This works pretty well for PvP and PvE. I rather have the ability to reduce damage to the most common attack (why Resist Energies is taken later) and felt I could live with taking damage from energy attacks with Dull Pain and Health slotted as they are. Tough Hide only adds to bein hit so I wasn't as important to me. All SO's are listed at lvl 52, but I do have 53's in some of my attacks and End Rdx's. Also, this was a respec build so the slots may look funny. Again, I've taken this toon out in both PvE and PvP (Warburg) and pretty satisfied with the results. while not a pure tank anymore (I define a pure tank as not needing non primary pools for def) I make a good Brick (if you know where that reference comes from

)
