If you're a druid and are doing the Apexis Emanation daily quest in BEM, you can exploit it as follows...
Start quest normally in human form, and once you have deposited your shard and it begins, go into flight form, and viola! Begin clicking the things as normal, while you're flying.
You may be asking how this is useful.. Well, if anyone attempts to Crowd Control you while you're doing the quest (to make you fail it) they cannot, since you're immune to everything.
Small exploit, but fairly useful.
