Strand and Wintergrasp both seem great to me....I don't use vehicles in either and just run around destroying vehicles/turrets, seems to work great in my experience. Whenever I do pug WSG its fail, but rolling with guildmates/friends usually is fine just playing as a big zerg. AV i've always avoided, Horde on my BG just has a defeatists attitude about it so we never win. EOTS is good, AB is ok...

As for S5, im looking forward to it. I do think pally healer would be pretty sweet to have as the bubble would be huge with the level of burst damage out there right now (rogues doing 10k damage in 2 seconds) if you have a holy pally friend, I don't (they all rerolled or went ret long ago) so I'm going to be playing with either a disc priest or resto druid. For gear setup im stacking all stamina
