Taking It on the Chin. An Intro to Tanking

Great guide. Made me want to roll several tanks at once !

I do have one question - you mentionned that Elec melee allowed for some interesting IO tricks, but I didn't see any details on those. Care to expand?

Glad you enjoyed it.
Elec melee has several powers that take stun, sleep, and kb sets. These include a number of useful procs. The Sleep:Chance for Self Heal (at work so I don't remember the exact name) is a good example. The Feedback:Chance for Recharge in Thunderstrike is another good one.
The next update I was meaning to revist IOing tanks, since the advent of Alpha slots, and the +dmg one in particular makes it viable to use many sets that would have been vendor trash in prior issues.
