heres my advice:
IF YOU HAVE THE PASSION DO THE FLYING JOB!!!!
Flight dispatchers are 'ground airline captain' positions, they do not fly and its ground duties. Yes FD (license holders) in major airlines are getting good basic pay comparable towards FOd basic pay, but why waste your effort of gaining your flying license? unless your going towards airline operational managment level?
I have my FAA flight dispatch license after obtaining my fATPL years back, but i told it for a backup and i just pratically did the written and pratical exams over a 1 week period in Dallas. Thats just for me to display it on my resume if i would to change airlines to work with.
Go do the flying job, gain the experience and hours then you move on from there... FD positions are always open to pple whom got flying experiences thats always a backup job for any pilots who has lose their liences....
Cheers!
Great Way to Fly!
