I think my arena dream is over.
Our 3’s team has become well – for Sh*ts and Giggles, and not something we want to work on getting right.
My enthusiasm for arena has died a little with the teams loss of enthusiasm.
But I found skirmish. I will always have skirmish. I don’t need a team, and I win some, and I lose some, and it doesn’t matter how crap I am, because I always meet someone worse than me in a skirmish. Though the Disc experience, and my holiday as a proper Shadow Pvp was a lot of fun.
However it’s easier to have my offspec as holy. I know I should do what I want to do , but it’s the curse of a hybrid. I don’t want to be swapping my gylphs, and my talent points just in case and not have it used. For now the rewards for having that offspec available to be used instantly outweighs what else I could be using it for.
Guess that means I am back to Healing LFG’s again for the shorter Queues because I don’t have to wait the 13-19 odd min like the rest of the dps. Fun times 🙂

You could compromise… Disc PVE does really well in PVP. I think it’s perfectly fine for Battlegrounds where Mana Burning is not as important; and depending on your partner Disc PVE is a desirable spec for arenas.
That said, I personally enjoy Holy, so just a suggestion.
