I used to have this problem too....now i use the following rotation so that no one can rip things off me at the start (esp THAT BLM that always loves to open the big guns XD)

Shield Lob -> Circle of Scorn -> Flash

If not using shield lob you can use circle of scorn -> Flash.

Problem with shield lob -> Flash is that both are on gcd so there is a gap before you can use flash after shield lob and this can be enough for mobs to go postal on your healer/BLM/SMN. Circle of scorn after shield lob allows you to fill that gap.

Sometimes you might have to position yourself so that all enemies get hit but it works for me almost every time. It allows me to comfortably start the enmity combo on one mob then Flash again to maintain enmity on others.

Under level 50, I dont bother with shield lob and just flash...because of the inconvenience of shield lob triggering GCD..
