No. That is not the reason. The reason is a spoiler so you'll just have to wait and find out.
You just didn't want Traya to face GO-TO because GO-TO is the only one Traya can't corrupt, mind control, or auto-win with by hiding on Malachor V. :P
Its interesting that you think G0-T0 is the one to beat though. Perhaps I underestimate him.
Why is that, just curious.
I think G0-T0 is the one to beat in this Kaggath. Assuming Malgus gets to the final, I think he's the only one who would be able to beat G0-T0
