Sorry for my "bad" questioning, I'm not a native englisch speaker.

The Accounts can't be merged, cause the first one was made with a fantasy name, I already tried it more then once, but it's not possible. But that wasn't my question.

Well, I thought about doing some BGs mainly. I just thought 5 DKs is easier to manage, then 4 DKs and a healdruid. On the 4dk & 1healdruid-setup, there a better options to level, cause I can easier finish dungeons. On the Paladinaccount is also the swift spectral tiger, so it's really a first world problem, which accounts to play.

On the other side, is unholy or blood DK (what it will be in legion, cause frost DK is playing with 2x1h sword) really playable in BGs? I checked some videos and all I can see is just frost DKs. So the other options would be 5 Druide (like 5 boomkins, maybe for leveling guardian druid, but I'm not really a big fan of guardian druid).

So there are 3 options:

5 DKs (unholy)
4 DKs (unholy) & 1 healdruid
5 druids (boomkin)

I would also get a licence of IS-Boxer, so now the question is, what is for mainly pvp the best setup?
