One of the fun things about Frenzied Regeneration is that unlike other HOTs, it can crit. I've always wondered why this is, and I figured if anyone knew, the people on these boards would.

My working hypothesis is that because it's classed as "School:Physical" it's not actually a HoT, it's a series of individual heals that count as physical 'damage' and thus are subject to normal crit rules.

Which raises an even more interesting question - what is it that determines your Frenzied Regen crit rate? Is it your spell crit, or your physical crit rate? Testing is very difficult with a rage-dependent skill on a 3-minute cooldown, but I wondered if anyone had any insight.

Weird, I don't recall ever seeing it crit. That would lent me to think it's due to spell crit, since I have approximately 2 int in my bear gear.

I think your hypothesis is right, at least practically speaking. It's not a normal HoT, as it requires a "check (rage)" for the regen to occur.

And it's definitely not physical damage crit rate. Spell crit is more likely, though, as you stated, annoying at the very least to test.

I thought the same after seeing it crit where as every other HOT in the game cannot crit so I do believe they count as small heals because were as a HOT is guaranteed heal for X frenzied is various and all dependent on your current rage.

And I am pretty sure its spell crit rate

in bear form, I (a druid I can borrow :p ) has 28% crit rate +-, if it were melee crit I would never lose a duel to anyone anymore.

I see it as a series of small heals, each requiring 10 rage for the full effect.

It also works with the talent for improved regrowth. (This might be an accident, or could have been fixed since I dropped the talent) While I had improved regrowth I saw roughly a 60% crit rate on frenzied regen. After dropping the talent my crits dropped significantly. So my guess is that it is considdered to be an equivalent to individual regrowth casts or some sort, but would definately seem to be dependant on spell crit rate.

My better half noticed that she gets more critted frenzies when she's gobbled down a moongoose pot ;O She also doesnt have any spellcrit gear on, is specced full feral (solo char) and see's around 2-3 crits per full rage frenzied regen as well, with 23% melee crit.

Improved Regrowth having an effect seems unlikely to me, and I dont know if its melee crit as much as random chance or w/e that is having the effect either, just thought I'd mention her experience and see if it helps out ;]

Sometimes I always do a double take, because I think I've seen it crit before. Doesn't happen very often at all, but I do believe it can crit.

Don't forget that the character has an innate amount of spell crit without wearing any spell crit gear, and if she is wearing any int gear that increases spell crit chances. As for the mongoose, I find it hard to believe that a 2% to crit boost gives any noticable increase unless this was tracked over a large series of tests. Otherwise, it could just be luck.

It may not be the case any longer, but when I was specced Imp Regrowth, on hundreds of casts of Frenzied Regen I consistantly has extremely high frequency of crits. As soon as I specced out of it, the crit frequency decreased dramatically. You draw any conclusions from this that you wish, it is just my observation. Maybe someone wouldn't mind speccing into it and trying?

As a Warrior, I noticed I could crit bloodthirst heals if, and only if, I had Nef's head buff (+10% spell crit.) I would imagine Frenzied Regen worked the same way. A rage dependant heal that works off of spell crit.

Yes, it's based on spell crit. Oddly, it doesn't seem affected by some -Healing debuffs (curse of the timbermaw iirc) nor can it be prevented by Silence (unlike Taunt ...)

Fun thing with Bloodthirst, you can get Songflower Serenade, Rallying cry of the Dragonslayer, and one of the DM Tribute buffs (Slip'kik's Savvy I think) for a 18% crit chance on your Bloodthirst heals.

Healing effects based on a variable are treated like an ontarget dd spell of a generic school. Vampiric embrace functions the same way, critting and being dependant on damage dealt. Neither directly scales with +heal or +dmg/heal gear (though VE does in a roundabout way).

I'd say that's doubtful, as far as I can tell with HoTs at least, any healing debuffs like MS are applied the moment the healing is done by the spell, not the moment you cast the spell. Of course, the mechanics aren't exactly the same for Frenzied Regeneration, but it seems unlikely it's the one exception to the rule.

Another fun fact is that siphon life, death coil and drain life is unaffected by mortal strike :)

IMO its a yes and no on this theory because its not "physical damage" because you crit for an extra 50% healing and that means its a spell effect.
