No they don't go to waste. But I wouldn't say that they stack, either. During the battle, it depends on from which equipment your frenzy is being activated. And the time being for which your frenzy is being activated would remain same too. Suppose you activated frenzy from your armor and then you recieve a head hit and you activate another frenzy from your helm. Then your damage from the next hit would include your two frenzies if they are still activated. But their are great chances that one of them might get depleted over time and you might hit the opponent with one Frenzy only. That's the reason most players use frenzy on all their equipment so as to use as much frenzies as they can.

Sorry if you find this post long and confusing.
