I just saw the spell showcase video from stormblood and, I'm very confused

When I started playing the game I rolled as a BLM because I thought it was a cool looking job.

Then I discovered Astrologian and fell in love with the sakura card captor feeling.
I then leveled every other job (still working on this horrible monk job though), I wanted to have the freedom the pick what job would suit me best for the expansion.

When the red mage was announced (without much surprise), I felt that this could become my new true love, and then... and then this video showed up.

After seeing all these new skills, all these cool revamped spell effect.
I am now very unhappy.
SE, why did you give such cool looking spell to everyone? (Except monk, but I don't care, monks suck)
My choice should have been simple... Yet it isn't
My heart is confused now.
I need to choose, but... I don't know if I can, if I'll be able to... It is too hard for me now.

What should I do? How can I know which job truly fits me.

Please, minna-san, grant me your strength to help me fight the doubt that SE installed in my heart!
Onegaishimasu!
