Please don't let the title fool you - I don't "hate" Composition, I just feel it is often misrepresented.
Let me elaborate, and as I will in general do, I am talking about Warhammer 40,000.
1) Warhammer 40,000 operates with a published set of rules and codices that are available to anyone who plays the game. More importantly, anyone attending a tournament is probably going to have a rough grasp on this game.
2) People play the game of 40k differently everywhere you go. There's no right way to play it, b/c it is not a professionalized game. This isn't Baseball, or Football, where there are a prescribed set of rules and regulations that apply to the sport anywhere you go.
Or, maybe it is. If you went someplace and watched them play baseball, and runs were worth different points levels depending on how difficult or not the event host considered the scoring play to be, you would be a little perplexed. It might be interesting, it might even be fascinating ... heck, you might even want to grab a glove and a bat and participate. But wait, they don't use gloves and bats. Instead, you have to catch balls with your bare hands the way the original players did. You have to use a railroad crossbar as a bat (seriously). It's a small lead ball that they use, not a Rawlings Baseball.
Upon inquiring about the odd equipment, the event organizers tell you that this is how the game is SUPPOSED to be played, and that it encourages a totally different and unique approach, and it's way more fun. You protest, that you've played baseball the same way your entire life, and how are you supposed to excel at this new version of the game?
You can see where I'm going with this.
It's totally functional and alright to play the game of Warhammer 40,000 differently, but as soon as you diverge materially from the rules of the game, you aren't playing the game anymore. You're playing YOUR version of it. It's not Warhammer 40,000. It's Tourney Organizer X's Warhammer 40k.
Interestingly, you can't actually avoid this. No matter what you do, it's not going to be pure 40k, and probably for the best. Nevertheless, Composition requirements and limitations greatly exacerbate this problem.
If you don't like that 40k allows for a wide variety of army builds, that range greatly in terms of their competitiveness, please consider avoiding the tournament notion of the hobby, and continue to play among friends who believe that you should only build lists a certain way, or rather should never build them a certain way (6 and half dozen as those opinions are).
Warhammer 40,000 is - for better or worse - written by amateurs. The people who craft the game are not graduates of the Oxford School of Wargame Rules Writing. In some (or many) cases, they are not even fully college educated. This isn't a knock on them, but it's a wake-up call to the fact that they aren't pure pros - their rules aren't perfect. Acknowledge that the reason for this isn't that they are stupid. They're just people with jobs. Regardless, all of us tournament organizers nationwide are ... ALSO not professional rules writers. We're also amateurs. We have our opinions about the game. We are not BETTER qualified to regulate a game that we didn't write in the first place. We may prefer it were different, and that's fine, but consider strongly whether that preference - as individual and opinionated as it is - belongs in a COMPETITION.
Wherever possible, I will keep my own opinions about what units or army lists are best or most creative or how it should be done OUT of building a tournament setting. Wherever possible, I will encourage people to play by the rules of the game out there.
The most important "why" behind my stance on this is as follows: A competition should be competitive. Professional sports are competitive b/c their rules are codified and regulated across the depth and breadth of their pursuit. With only subtle variations, the game of baseball is the same for a 13 year old as it is for a 33 year old. You can learn this game via the official rules, which anyone can access. First base is first base, a run is a run, a strike is a strike.
Since everyone who attends a tournament is likely in possession of and is aware of the rules of Warhammer 40k, and the details of at least their own codex, it best supports a competitive and reliable environment on the gaming front to utilize those rules, instead of instilling our own homegrown restrictions.
Will we develop a FAQ to answer questions not addressed by GW? Probably, to as much of a degree as we absolutely must. Will we consider different restrictions for Warhammer Fantasy, where the game is *arguably* far less balanced? Possibly. Will we come up with missions and objectives that are not identical to the ones in the Warhammer 40,000 Rulebook? Again, possibly.
What must be said, though, is that composition will likely NOT play a role in the Warhammer 40k side of our event. It is just too extreme (unless it's mellow to the point of being pointless) an amendment to the BASE game. It is in and of itself unfair to the wide margin of participants, who effectively must attempt to investigate, comprehend and react to a set of entirely new army build restrictions with whatever time the organizers give them for digestion.
What are your thoughts on composition?
