I think by "prefix" he means "name of". Such as Adept, Bulwark, Steadfast, Vigilant, etc
^^ This. sorry for using "prefix" incorrectly. All I was thinking is that, by now, most players/crafters have figured out what stat combos they like best. Since there are a zillion combos, what names are the most sought after.
And yes, I have been paying attention to what my toons need. My tanks benefit from Bastion and it's cousins that trade off shield/defense/absorb. Personally, I find my healers need alacrity and crit, although I'm sure what names are the best for that combo.
Anyway, thanks for the input folks !
