Ok since theres a bloody thread about it, and the age of reality TV means everyone wants to make everything public, I'll share my thoughts in response.
A) I have faith in my comp system. Cam knows as well as anyone how punishing it can be, he, Rohan and Matt finished 1,2 and 3 bottom comp last year, and I think finished in the bottom half (Matt picked up the best general trophy too).

My request was to change A) either one prince, or

one oblit pair. Twin lash mixed with template weapons is THE bad comp combo of 5th Ed (so far). Whether this is perception or real is a moot point. Six players will have to play against that list, and whether theres truth in it or not, they will have the suspicion, if they lose, that they were beaten by the cheese, rather than the general. And, if they lose, they will probably feel sh!te about it for a while. I dont forget that my players are paying customers, theyre paying me to have a good time. One bad army can take that away, and this by reputation alone, has the capacity to do that.
C) Ive used a single lash before and oblits, and had to stop I felt so dirty for doing it.
D) Player comp is 20% of the overall mark. Whether the combo is good or not, the perception is that its game breaking, and this essentially means that Cam has no chance in the tournament overall (as, if expected, his list is marked harshly). I made the recommendation as much for his benefit (ie wanting him to do well), though knowing full well that he'd ignore me. Hence why Ive let it through.
Hope that explains the myriad of factors that led me to ask Cam to think about his list again. His reply gave me food for thought, and hopefully next year he paints something other than the cheeze

PS Matt, I think you vastly overrate the effectiveness of the Kroot codex.
Cheers,
Ben
