Glyph of Lightning Shield

After the Glyph of Unleashed Lightning was removed on the PTR, Shaman got a new Glyph in it's place: Glyph of Lightning Shield. Here's the tooltip as it currently stands:

• Glyph of Lightning Shield causes Lightning Shield to reduce the amount of damage taken by 10% for 6 seconds after Lightning Shield is triggered.

Previously, it just passively reduced your damage taken by 10% at all times. We should still be able to keep 100% uptime on the buff as long as we're being attacked.
