[MONK] My issues with the MONK, especially compared to other jobs.

Also, Disciplined Fist should be locked while doing your Perfect Balance combo, all the way up to the finisher. The 'natural' rotation of pressing PB on cooldown has the player drop disciplined fist and it feels rather cumbersome to design a mechanic like this, regardless of the player's ability to deal with it or not.

No, it doesn't. There is no need to drop Disciplined Fist when playing optimally unless you're somehow avoiding even the slightest scrap of SkS.

If you're dropping DF, it's almost certainly because you're never allowing yourself to invert your Lunar/Solar order. You can and should be adapting it, especially if you're restricting yourself to extremely slow GCDs. Even then, it doesn't force PB delays, just the tiniest bit of extra thinking.

Why can I not continue the combo from the skill I last used?

Fair question, and with a simple but disappointing answer: They tied the formlessness to Blitz instead of to the consumption of the third charge of PB itself with Blitz just not consuming that buff, causing a small loss to available nuance in endgame but a major oversight to the pre-Blitz experience.
