Tuirseach Veteran - Not The Problem
I notice you changed the tag back to Support when it SHOULD be a Soldier card.
The imbalance seen on the PTR wasn't because Veterans had a soldier tag, it was because the Beastmaster card had a Tuirseach tag. You were getting 4 point Beastmasters spawning 11 point bears, solid, resurrect-able 15 point bronze with zero interactions.
Why not just change the clan tag on Beastmaster? If it wasn't Tuirseach, it wouldn't get buffed by Veterans and the problem goes away.
