I'm just now finally able to play again after a very busy work-weekend, So I'll log in now to see if that's a issue.
Is there anything I need to look out for aside from the blinking? (as in, is there a certain thing i need to look out for? )

Thank you nevertheless for the pointers in the right direction, Reading this did make me realize that sometimes my controller has 2 issues at a certain point, but these only (sadly) occur during playing FFXIV
*Either the Controller "loses" it's connection from P1 and after a brief moment shifts to the P2 slot
*Or it switches from P1 to a entire green ring in the middle of my controller and takes a long time to reconnect at all.

I'll open up the device manager during the time i play (although I'll have about a hour left to play before I really need to hit the fleabunk)
I'll keep everyone posted in here!
You just need to watch out if Device Manager refreshes. If it does it means the device is reconnecting and that there is something in FFXIV that is causing it to drop. My controller been doing the same in FFXIV and only in FFXIV.
