Potency for toons with no debuff abilities

As mentioned above, potency helps TMR stick - that's why QGJ and Rex have need of good potency. It's a must for Teebo, especially on the Tier 6-7 Rancor raids - he's got no debuff ability but an awesome TMR move (if omega'd, still pretty good without) that only lands with good potency (65% or higher I'm told).

Some characters without TMR or debuffs get some potency from gear...it's minimal and not really intended for that purpose (it's the other stats on the gear that matter).
