Just had a read through the pack. The ADR rules are... interesting...
I'm sure they definitely won't be used to push a person's personal prejudice against a Codex..
I can assure you that this won't be used in any such prejudicial manner.
It's just a new format on comp scoring that has enough flexibility to deal with the fluffy lists that can get dinged by a more rigid comp scoring system, and also means that you can turn up with a nasty list and still win... as long as you back yourself to beat all the other filth lists in the tournament too without getting any easy rides in the early rounds.
Obviously what we're looking to avoid here are triple heldrake lists, leafblowers with 3 full supporting vendetta squadrons, or anyone claiming Eldrad and 5 naked dire avengers is fluffy as an allied detachment for Grey Knights.
Each list will be looked at objectively by myself, Hymirl and a neutral third party whose identity will remain anonymous (at least until they've been recruited).
I assure you that no-one is going to get punished for using the wrong codex.
We just want the definition of friendly to be "everyone has a good time" rather than "I'm bringing filth, but I promise to shake your hand and smile cheerfully while I'm crushing you."
