ArenaNet:Skill feedback/Warrior/Fixing defensive stances

The last update completely removed warrior defensive stances from the game due to abuse from monks.

Learn to program, Anet.

First of all, move them to Strength and revert the nerfs. Ever wonder why the same problems don't happen with Ranger defensive stances? That's because all of the useful ones are in Expertise.

Now there's another problem. Thanks to the idiot who decided to give Strength a healing skill for 2 attribute builds, this would give warriors defense and healing in the same line.

Solution: Add "All of your Strength stances are disabled for 12 seconds" to the defensive stances.

- Alternate solution:

Add "Ends if you use a skill on another ally." to all defensive stances. So warriors can actually use them, but monks can't heal others while blocking. Again, revert the nerfs. It's so simple to program.

Oh, and fix Shield Bash while you're at it.
