"only XL-4"

If you're going to pick a Warrior instead of Dessa, then Tiraxor is the only choice. Kreg Hex is a noob pick for HL+U.

Tiraxor might be better in the first week. But what about after that? Kreg knows his stuff... he deals so much damage that everyone panics. And 6LM is a late-game creature; Tiraxor doesn't stand out there, but Logist does... although I didn't like him, and I wouldn't pick him at the start.

P.S. I looked at your reports, and you lost the last 3 games you played with Tiraxor... just saying.
