Top priority? Maybe not. It's always important to unlock new areas since the latest is usually the greatest unless you're hunting something in specific. Though it's also a good idea not to burn yourself out trying to progress too fast, rushing past 3 areas and complaining about the 4th being stale.
I'm quite happy about the skill tree bit. When I read about Techers I was excited to unlock and play one but bummed at the idea of losing my Force's ability to regain PP while still charging my next attack
