OMG I thought I was the only one who ever did this!
I have a 64 (going for 70) UM tank defender, and I too put 6 debuffs into a globefish. I too am not so rich, so I linked: toxin, slomo, curse, jinx, panic, and crawl. I LOVE it for PvP and PvE. It makes Panic, the spell, a distance attack for several debuffs. And sometimes a single cast of panic puts on several debuffs at once before the mob or Fury gets to me. I enchanted to get more attack power, tho for tank this is opional, but after using up all 6 slots, it IS an option to get attack power still. If/when I can spend more, I'd like silent, pain and darkness as well. So basically, I totally agree with everything Davewave said and love debuffs for tank build defenders.
