As a warrior, I noticed that Thunderclap is a spell, but for some reason mitigated by armor.
The result is, for a mob 1 level lower than me, thunderclap damage is lessened like 35%, which is a huge amount. Example: Tooltip says 206 damage, but it hits like 135 at level 63 to ordinary mobs in zones. ( With full 5 stacks of sunder armor, it increases to 155, still damage is reduced by %25 then)
If it is a spell (which is, since its damage can be increased by using wizard oils), can you please correct it, so the damage is not mitigated by armor please, because we warrior tanks are using it as our sole AOE threat. (Please ignore some people who says its a mitigation skill, we warriors use it as aoe threat generator also), or can you please lessen the mitigation, a 35% damage reduction is too much.
Just imagine what could happen if consecrate damage was mitigated by armor. (Or any spell; paladins and warriors can turn casters into shreds)
(I know, in wotlk it started to crit, and turned into a skill, I dont want that btw)
Thunderclap is physical though so not a spell, as you can see from the dmg being increased from sunder, take into account that defensive stance also decresse dmg by 10% and there is most likley the problem you are seeing.
If it is increased by the oils thats most likley a bug seeing as clap is classed as being of the physical spell school. If you are using clap in defensive stance the loss you expierence is dmg is mitigated by the increase of threat you have in defensive stance.
You do know that spells also have a chance to crit right? It have always been physical and never have been anything els and you wouldnt want it to be nature dmg for example (like every other thunder thing in the game). Physical “spells”/ abilites = reduced by armor, whle concecrate is holy dmg and is not decresed by armor, as a warrior tank its important to think about all our skills getting reduced by armor.
With the numbers being from battle stance im guessing its just becouse things have a lot of armor.
When it comes to the crits im fairly sure I have seen it crit a few times but I could be wrong and with how buggy some things were back then and how buggy somethings are right now its bascily up in the air if it was inteded to crit back than and didnt or if it wasnt and is doing it now. A dearly hope that all the database things I found about clap is right though and its physical becouse using oils for aoe pulls and then removing them to put on something els or to be able to get usage out of a totem would be horrible to do all the time in raids.
I have seen these in tbcwowhead thunderclap lvl1 comments, mentioning spell/skill/ wizard oil thingies.
These are from the past of course, wondering if they still persist today:
This skill is categorized as a spell even though its damage is mitigated by armor as its considered physical, lame.
123 base dmg (rank 7) +42 spell damage (superior wizard oil).
As you said, hopefully, they will clarify it. My guess is that the rank at level 6 is from lvl58, and when it hits the 62 lvl mob, it is kinda decreased. I also see there in the modified by talents, there is impale too which is kinda weird.
Patch 1.3.0] Now causes Physical damage instead of Nature damage; damage increased; duration increased with each new rank.
Patch_3.3.3) (2010-03-23):** This ability now counts as a ranged attack, granting it double damage on critical strikes instead of 150% and ranged miss chance, and still cannot be dodged or parried.
TL;DR: The ability does Physical damage, but the hit chance is on the Spell Hit tables !
