Data Centers aren't queued together in Duty Finder?

[CGX]

Hey, returning player here. I decided after coming back I would leave my OG server for Seraph since it was new and I didn't RP much and I was on a RP server so I figured I would go elsewhere.

I'm in Stormblood for MSQ and got to a trial (Pool of Tribute)

Waited 45 mins in this queue...which doesn't feel good because I have to do it to progress. It was silent the queue never popped. So I asked a friend how I could get it done.... and they said to visit another Data Center...and I tried it and the queue was 5 mins.

So...why isn't duty finder cross-datacenter already? (or however you would say it)
Are there technical limitations?
What are their plans with Dynamis? Did I make a mistake?
Did I just move to a dead Data Center?
Gonna have to travel to a more populated one every time I want to a do a story dungeon or trial?

Can I revert this move by customer service/GM.... I had no clue this would be the outcome.
