Tusken synergy bug/Incorrect description

Arube

I don't know if anyone checks this sub-section anymore, but I encountered a possible bug with the Tuskens in a GW match. In the attached video, you can see Tusken Raider using his assist (which is supposed to do 75% more damage if another Tusken assists) and calling on URoRRuR'R'R and hitting 3559. Then using his basic URoRRuR'R'R deals 3645 damage.
Am I not correct in assuming the hit should have been near 6000? Or is the description mislabelled.

I run tuskens as well and I've noticed the same problem. They hit the same on a bonus damaged assist attack as well as their normal attack.

Five have the same problem... And no one care ....
I created 3 post on it and no reply + 10 view
They are not played so all don't care

@EA_Jesse If I could get some response on this, that would be lovely. I'm going to assume it is a description misprint until I get word otherwise.
