Thank you for your reply.
What you probably missed is that in 7 out of 8 cases screenshotted, the initial target was crit as well, and not once that critical damage exceeded 1k. At the same time cleave deals 2-3 times more damage to additional target. Does the crit multiplier get applied twice or something?
Also, in the one case screenshotted when initial attack
didn't crit cleave damage is still 2,5 times bigger than the damage dealt to initial target.
Also, quoting from
https://wowwiki-archive.fandom.com/wiki ... ng_Strikes (even though I know that many developers consider wowwiki.com unreliable, but where else can you get a proper description of vanilla spells nowadays?)
-Requires Melee Weapon Equipped.
-Damage dealt from a Sweeping Strike will never crit.
-Sweeping Strikes will not cause [Execute] to strike a nearby opponent unless the nearby opponent has less than 20% health (does not consume a charge of Sweeping Strikes either).
-If you use a special attack like [Slam] or [Mortal Strike] on an opponent, it will strike the nearest opponent if you have Sweeping Strikes up. In the case of Mortal Strike, though, only the damage is dealt; the second mob will not get the debuff from the attack.
-Sweeping Strikes doesn't always work; if you don't see the damage above the second mob's head, chances are the enemies aren't positioned correctly. Try to move around so that they're close together and standing side-by-side to get the effect of the ability.
There is a line in patchnotes on same wowwiki though:
World of Warcraft: The Burning Crusade Patch 2.1.0 (22-May-2007): This ability will no longer be modified erroneously on additional targets by percent modifiers to your damage.
If that is what the issue is, then is it a vanilla bug that has been carefully reporduced here?
Would be great to know.
