I've done Wpvp on all my teams now and this is what I have found...

4x ele sham: warden towers are fine, and even the 500 honour WQs, you don't drop follow until in combat and then once you stop fighting you get it back again. I have noticed that my toons will start following me again even while still waiting for combat to drop. As such broadcast turning to face mobs is fine and you can just kill one set of mobs at a time to complete the WQ, it added maybe 10-20 seconds to the quest times for me. Actual PVP, unless I get the drop on someone and kill them before they reach me, its a no go.

5x affliction lock: The exact same, I will just run into an area with a lot of the warden mobs around me then tab target them to dot and wait for them to die. Actual PVP, they don't do too badly. I only need to face the target for 2 spells and thats drain life and drain soul. To be honest I can insta cast 2 dots each and unstable affliction doesnt have to be facing either. Drain soul/life I can use broadcast turning while spamming the spell and eventually they will all be channeling it (the drains are nice because once you start, you dont have to keep facing the target). I can also press my interact with target macro once then backpedal to quickly face a target if i want to. If I ever get kited really well and kept in combat, I accept the loss, otherwise if i can i mount and try again. NOTE: 5x curse of fragility still stacks and it's hilarious.

Both these teams could use a pet to follow if I want to chase someone down, but generally not worth it.

Melee teams: Thesehave no dramas at all in WQ pvp areas, mostly. Interact with target everything and follow strobing puts them back on my leader. The difference is between pve and pvp fighting. Combat with any human player takes a lot longer to drop combat with, and even with it dropped you still get the 'cant follow someone in pvp combat' message. The way around this I best found was to just kill a mob nearby after killing your gank target. The stat squish has helped because my lower geared teams (IE: my lvl 105 dks) can actually stand a chance against geared people. My two teams of pallies and dks are fine with chasing people, but they don't usually catch them.I haven't even needed to use a pet for follow yet. (Have found I can take 4 dks into a BG with a friend, I use a 2 seater mount for my main and he uses a 3 seater, 2 of my guys jump in with him and I take 1 and we just hop from battle to battle like that. AV and IoC are best for this or just defend blacksmith).

Overall the changes aren't too bad, twinking is good again in the lower brackets and the stat squish has made fighting fun for me again, and the follow changes haven't ruined the game for me, just made it a bit harder is all.
