Wow, This got a bit ugly didn't it.
By all accounts it seems that what the OP did was legal by the tournament rules, dried and cut.
However, that said it seems that it is a bad to score a win in a tournament.
I have played a what I understand to be a VERY respected wargame for some 6+ years now and back before I played it it's tournament scene suffered from what was called "VP Sniping" where one side would kill a single model (Usually totally around 5% of the game size) then spend the rest of the game do their best to avoid engagement and thus the lose of VP's while the other player would try to get back the VP difference without giving out more VP's while doing so.
This caused the tournament games to become dull/ boring barely engaging affairs, and the game suffered because of it.
It will happen to this game as well, if FFG doesn't change the way tournaments are scored/ played.
