You don't understand a god damn thing at all... the whole point is that BLMs DO NOT need Gaiters to kite. Well if you are a complete moron and happen to nuke Fortitude when its standing right next to you then maybe you will need em to survive, but if you have the sense to cancel your nuke if the NM comes close while you are casting then you won't have to worry and can just recast from a safe distance. I guess its fun to play w/ no sense and just nuke and run whenever you feel like it, but the whole argument is that gaiters are not needed if you happen to pull hate and need to kite.
edit:
In this case it did, and Andrinne is too far away.
You don't need gaiters to outrun a vorpal blade... lol
