Guild Wars 2

Just got my Ele to level 75 and the final push to 80 is on. I want this guy to be a staff support character in WvW since my Ranger is my solo roamer.

Elementalist is quite an interesting class that seems to have quite a few subtle nuances that I am slowly learning. That being said, here is my first real attempt at a build. I am completely open to criticism and/or advice.

Note: This 100% for WvW

Thanks for any input

Edit: Question about Inscription. If I used Glyph of Harmony while in Earth, would that be 4.5 sec of protection + 4.5 Sec of protection because of Inscription ?
