Now this might sound like a twisted idea to use strength trinket on a hunter but from the looks of it...
It gives 7% (8% hc version) critical damage, haste and mastery on equip at all times. The proc is standard 20s strength on 110s ICD.
Someone should really sim this. STR still does increase AP as much as agility does, you just won't get the extra crit during proc. I think those 214% damage criticals would actually outweigh the extra crit gained during agility proc :O And you do that much crit dmg at all times, not only during short window of time.
We don't have agility counterpart for this trinket type. Anyone tried it or have some sim data on it?
