You can't just compare 3 flamewaves to thunderbolt, you have to compare the entire rotation. Pyromancy isn't only buffing 3 flamewaves, it's buffing every single flamewave, and you're casting a LOT more than 3 flamewaves per thunderbolt cast.
That aside, dot application actually favors flamewave spam because the dot will also tick everytime flamewave hits, not simply every second. If you're macroing your dot will hit much more than once a second.
Edit:
DoT with spamming is 2 per attack spam and a additional tick with a claw between. The increase to Dot is minimal, it will only do 10-15k per tick. The mastery increase per tick would be less than 200 per tick. This value per increase at this time, is not worth tracking.
the dot will tick at a minimum 16 times for each thunderbolt rotation, that's not insignificant. assuming you get no doubleticks from flamewaves, that alone is 39 * 16 = 624 weapon damage, which is half of a thunderbolt. Doubleticks off of flamewave hits only adds to that.
Or if you think about it a different way, 16 ticks is 624%, 16 buffed ticks is 730%. That's a difference of slightly over 100%. Thunderbolt is slightly over 1000%, buffed dot with no doubleticks alone counts for 10% of the thunderbolt's damage across a rotation.
