Describe the Issue: Placing Talent Points in the Opportunity Tree, as a Rogue, only seems to affect the weapon damage percentage portion of damage dealt by an ability (i.e. Backstab Rank 2 with 150% base weapon damage and 30 bonus damage--placing points in Opportunist increases the weapon damage portion but not the additive damage).
How to reproduce: Examine the damage values of the Backstab Rank 2 ability--I believe Rank 2 Backstab, available at level 12, is 150% weapon damage and 30 additive damage--place a point in Opportunist. See that the weapon damage goes up, but the additive damage does not (at least in the tooltip). This also appears to be the case with the Ambush ability.
How is it supposed to work: Both the weapon damage and the additive damage should scale up by up to 20% at 5/5 ranks.
Character the bug occurred on: Pick a Rogue, any Rogue, but my character's name is Bosom.
https://www.wowhead.com/classic/spell=14075/opportunity#comments "Only Weapon Damage + Attack Power Normalization gets the damage boost - the fixed damage added on to the backstab / ambush does not get increased with Opportunity. Backstabs will be at 180% weapon damage + bonus and Ambushes at 300% weapon damage + bonus."
Seems to be the way blizzard made that talent.
The talent correctly increases damage by 20%. The tooltip does not seem to update the flat value for Backstab and Ambush as it should.
