It seems like every year we have one or two models that are less than awsome. This might be due to less skilled modellers but usualy it seems to be a time crunch every year one side or the other is all hush hush about some huge crazy superheavy or air force or gargantuan creature that one of its players is building, something they have spent months working on. Then a few weeks before the megabattle word leaks out that they are building it and it will actualy be there and the opposing side relizes that if said model goes unopposed it will be a game ending unit so with 2 weeks or so till game day one of there members changes there list and tries to throw together a model that took the other side months to build in just a few days, hence it looks terrible.
I think alot of this could be avoided if both sides where required to announce a few months in advance mabye by the end of march for example, any extreamly over the top units, or data sheets mabye any single model over 500 points before upgrades.
