I think better siwtch Killhare with JF, so that id both (JF & Killharre) mana charged, JF 1st before Killhare.
Freya - JF - Telluria - Killhare - Gazelle
But then just like @Mr.Spock said, Gazelle is not designed for defense.
Although in Poll best one is left flank though 
Here is the 
link poll Gazelle. It is just a reference, no big deals.
In my experience, I have maybe around 3-5 facing Gazelle defense in raid without any problem, she cast and I do not find problem. Not scary in defense.
