I agree with most people that a few things need to be tweaked with the Gladiator. The Apocalypse book specifically says that the rules there are intended for games of more than 3000 points. I like the idea of splitting the Gladiator into two, one 3000 and one 2250. Having 8 5" Strength D templates in a 2250 point game is overpowered. Did I whine about it this year? No. The rules are the rules, and the Gladiator specifically stated what was and wasn't allowed. I have no problems with people that brought Reavers. I did enjoy Mission 3 which gave everyone a vortex I did enjoy mission 3 which gave everyone a vortex grenade, I feel this gave people a chance at destroying the Reaver (I did in this game, at least). However, now that the 2009 Gladiator is over, I don't see anything wrong with having a discussion about what to fix for next year, so I don't think any of us are breaking the first rule of the Gladiator!
Not being able to move through flyers is a must fix.
Not being WYSIWYG is completely unacceptable. I did not complain about it when I faced one of the Flylords, but it states that everything must be WYSIWYG in the rules for a reason. If some of us have to go out of our way to convert models to be WYSIWYG, all of us should.
If the Gladiator is not made a straight-up Apoc. tournament or split into two, perhaps you should consider not allowing Apoc. rules and only allowing the older IA rules. Strength D and 10" templates, unless I am mistaken, do not exist in these rules. Also the points costs tend to be higher which, as already mentioned, will discourage people from taking them.
Another possible option would be to limit the points that are allowed to go to super-heavies and gargantuans. Maybe allow for around 750-800 to allow Stompas, Warhounds, Revenants, and Baneblades. Or if you don't want titans present at all limit it to 500-550.
My personal preference would be to increase the points limit to 3000, make it an apocalypse game where everyone gets a single strategic asset to counter the super-heavy units (I would still disallow formations, especially ones that give extra assets: the space marines commander one and the seer council get ridiculous). Having a 2250 game with no super-heavies allowed would simply be a miniature version of the 'Ard Boyz event. I would like to see the Gladiator remain a distinct event that you can only find at Adepticon.
Overall I thought the Gladiator was very well-run. Thanks so much to the organizers and all the other volunteers who helped throughout the weekend. The missions were nasty and the lists were nastier. I expected to see a few Reavers and wasn't surprised to see them finish so well. There's no point in complaining about what happened this year, but as Gladiator 2010 is being planned it is good to take a step back and consider possible things to change.
