Once a melee zones in on a BLM what tools does the BLM have to get away?

blizzard ii(for bind) has cast time
freeze has a cast time
not sure how the new pvp sleep works but probably has a cast time?(3 min cd)
lethargy is the only tool that you have w/o blowing cds! maybe pvp sleep if its instant.

so only way to kite is with cds:
1) swiftcast (1 min this will work)
2) surecast (30 secs but can be silenced?)
3) the pvp skill where your casts are uninterrupted for maximum of 20 secs (5 mins immune to silence? idk)
4) pvp sleep (3 min if its insta cast)

BLM struggle is real.
