I am a hardcore tournament player who has played in Rogue Trader Tournaments from Salem, Oregon, down to San Francisco, Sacramento, Los Angeles and San Diego, California. I have also played in Jacksonville, Orlando and Tampa, Florida. Right now I am playing and living in Phoenix AZ, but the tournament scene is rather dead for a city of this size, so I might need to join a league.
I try to attend as many large tournaments as I can. Although the GW Grand Tournaments get a bad rap, I enjoy them, and my goal is to win a GT one day. Also I attended Adepticon in Chicago every year and if you are a fan of 40k, this is a must because there is no other event quite like it.
In my comp article I wanted to say that I was talking about 40k. Fantasy is a mess right now, and they may need some kind of comp system because they have 3 army books that are overpowered compared to of all of the others. I know that GW wants a little bit of codex creep to sell new figures, but they are doing a very bad job of balancing Fantasy right now.
For the most part I think 40k is in good shape as far as balancing goes. To give an example of this here are the results of the Heat #2 of the UK GT that took place last weekend. Remember that this is a 1500 point, no comp, bring the hardest armies you can make:
1) Mark Burstall - Orks
2) Simone Di Tomaso - CSM
3) Kiam Reddy - Eldar
4) Felix Porras Munoz - CSM
5) Ricardo Bacelo Polo - Orks
6) Andrew Church - Blood Angels
7) Alexander Fennell - Imperial Guard
8) Manuel Andres Fernandez - Necrons
9) David Fairweather - Daemons
10) Gianni Vacca - Imperial Guard
We see that there are 7 different armies in the top ten. That is pretty good. Not only that but Necrons* who everyone says are a bad army had a good showing. Also I am glad that I sold my Heat 2 ticket to Alex so he could place 7th. J
If I have to point a finger at the imbalances in 40k have more to do with certain units instead of armies in general. When 5th edition rolled out, it made previously mediocre units very powerful. Nob Bikers, Seer Councils, Mech armies, etc. So I would say that if you were going to have comp, it would be to limit certain units, and not really punish armies.
*I like Necrons, they kind of play like my Eldar army. They can chuck a lot of strength 6 shooting down-range and they are fast and durable. At the Wild West Shootout I won a Necron army and I am tempted to play one, but I told myself that I need to cut my armies down to only 5.
