I've been wanting to comment on this thread for awhile, but don't know where to start.
So I'd like to state, please test out your idea's. A racial guild is a great way to do this or a large network of friends is also a good way. I've done both. Glorian gave solid advice. You have to build a network/community of player's that are willing to test out your idea's (be experimental) and that are not afraid of failure. Bounce idea's off each other. You will fail a TON in the beginning because there is a learning process involved on playing to your strengths. 6 man comps have rigid restrictions, comps based at the warband level are not so rigid. There is a style of play that needs to be learned to these racial groups/warbands. You also have to learn how to mitigate your weaknesses through smart play.
I'll state this on warband creation.
It is all about Pre-planning.
Always have 2 healer's per group, note you could have more then 2 healer's in a group.
Base 2 of your groups on AoE Ap damage (this is your bomb)
This could be mdps based or rdps based or a mix. There are pro's and con's to each. The bomb can be a combination of Ap AoE damage and AoE Morale damage.
Group 3 and 4 can be exotic or more ap AoE bomb.
If your bringing mdps always bring a guard with it.
Mdps groups cost more player resource then Rdps groups but mdps centric groups don't care about HTL.
Rdps cost less player resource and don't require a guard but have to deal with HTL.
4 rdps 2 heal is very valid for a group 3 or 4 in a warband setting.
Think on if you want to run a HTL warband comp or not. Pro's and Con's to this.
You likely want to run a HTL warband comp for a keep defense/keep offense situation.
Have different pre-planned group comp make up's for the 3 different phases of ORvR which are: Roam/Keep Offense/Keep Defense.
Potentially reconstruct the warband comp makeup. Mass gear swap/class spec/renown build/tactic swap to adjust to the phase your in.
Don't ignore your morale bomb's. You can combo m2 with m4 morale bombs especially with High Elves.
