Looking for leveling strategies for cata and mop

[Ravenoff]

Speaking of PITA gathering quests - how affective is loot-a-rang? While it requires 490 engineering to make, it says it only requires 125 engineering to use and its bind on use, so a single high level engineer should be able to distribute it to lowbish engineers.

I'm getting some spotty details on its workings - can one get away with /targetlasttarget? a comment on wowhead said it doesn't require a target as of 5.2, but I would expect a mouseover or something. (and its cast time was reduced to .1 seconds)

If it works the way I hope it does, with AOE looting, a global macro for all toons with this could make gathering quests less painful.

my engineering isn't high enough yet to try.
