I know Frenzy is an extremely popular skill for warriors because of the IAS without a decrease in damage. (increase in damage to yourself though)
I just want to know what some of your observations are in pvp.
1) How often do you see it being used in GvG?
2) In TA/RA and Heroe's Ascent?
For myself, I see this skill being used most frequently with hammer W/E's in TA/RA and in GvG. Of course axe and sword use it almost as much but its usually a good bet that a hammer warrior will be packing frenzy and sprint.

It's definately a PvP only skill imo, high level mobs slaughter frenzy users unless the monks pour energy in or take certain skills, and that's a very bad deal for the team.
