"I read a lot of things about how MCH is too proc based and RNG dependent to be reliable."

:O
That's a negative, sir. There are phases in your "rotation" where you're more RNG dependent, but it's neither something that particularly bothers me, nor is it anything other people judge the job on. It's certainly not unreliable, in fact it's arguably the ranged support of choice, not that BRD isn't viable. The variance in DPS caused by bad proc luck without ammunition is something pretty much never talked about...it's not the biggest deal.

As for BLM, it is punishing to drop that one buff, but that's a fight by fight basis - getting to know what's going to happen when, and adjusting your refreshes accordingly. Saving Swiftcast for emergencies also doesn't really hinder DPS. If you're in Astral Fire for example and only have 3 seconds left on Enochian for whatever reason you can quickly Tranpose -> Swiftcast -> Blizzard 4. As said above every DPS class has some kind of punishment for failing certain things, even if some are a bit more forgiving than others.

Stick with MCH/BLM and judge for yourself. *nod*

Edit: On the subject of Palace, people recommend it to get a "feel" for jobs but it only goes so far. Enemies die so quickly that dots and things aren't worth applying, also lots of downtime means getting a feel for buff timers on jobs like DRG and BLM is really skewed. You have maybe 1 boss to practice a proper rotation on but even they melt in no time depending on the composition. Take Palace with a grain of salt for judging anything other than "feel"
