The big difference between traya and other raid reward toons is that to a certain extent they are plug and play. GK works every where, so does Raid Han. Traya is a specific DS toon with little PaP ability. She can still beat Revan, you just need to think outside the box.
The issue is the AI being changed to never make a mistake and target any other toon. That's the real issue and a poorly thought out concept. Having one characters AI smarter than every other characters AI creates something more than a power creep, it's an intelligence creep...
They all need to be as dumb as each other, or as smart as each other, otherwise a blatant bias is created
