There was a decent amount of activity on the official WoW forums today - both US and EU - so we have a quick recap of the day's events.
A weapon isn't going to keep your 1300 team from competing with the best teams.
The change is being made to help keep the nice PvP rewards for the good PvP players, and the nice PvE rewards for the good PvErs. Having the weapons there is too tempting for PvE players to come in, not care about PvP, their team, or rating, and jump in just long enough to go for the weapons and then leave. It's not exactly in-line with the team and ladder based PvP competition the arenas are there for.
Also, there's been no announcement on a final rating. I remember hearing 1800 at BlizzCon, some people say they heard 1900, in any case it's likely to be around there but there's still no final number announced... or even if it's a definite and final change.
Moving them off to their own slot isn't something we're looking to do at the moment, but we are looking in to helping with the ... lacking quiver/ammo pouch sizes.
We currently don’t plan to release information through previews for patch 2.3 just one class at a time. Once 2.2 is released we look forward to providing information on all classes as the changes are finalized.
Are there any other skills that display this characteristic of affecting specifically Undead and Demon targets as opposed to only affecting Undead?
The only two I could find were Holy Wrath and Exorcism which have been mentioned and were changed in patch 1.9 (ahh, good old AQ)...
I'll try to find out if there is a reason why Turn Undead does not display the same characteristics as these other two skills which were changed.
