Tummel was much less PK oriented than previous thieves. He focused more on Drillmaster than hunting as he got older. Also, because of Drillmaster, he didn't stay at 42 as long as previous. Lastly, while Gergan could have chosen 2xdevious versatility, Tummel never got enough IMMxp to get DV at all.
Escaping your bearcharge: I wondered the same thing. After I saw your PK logs and everyone getting command denied, I went to look back at the log of our brief fight to see if you had missed, but I didn't log it. I don't think you did. Tummel had no skill to reduce lag that I knew of. Were you enlarged?
