I totally feel your pain here CrimsonReign.

I just did a few leves myself and they where hard as heck to do without dying. Even on one star.
After the ordeal I managed to finish the leves and got ran.. erm.. level 20 conjurer. (yay!) I then switched to Thaumaturge (lv15) and went back to the level 20 camp to fight ladybug thingies... And kept freaking dying. They where just 2 levels above me, which before patch where not a problem, but after patch my spells are only about 25% as effective as before. Damage spells went from 200 dmg, to around 50. And healing spells are the same. Sacrifice now take away as much HP as it heals when I cast it, effectively only healing me during the "regen" -effect.
I no longer use the TP-consuming abilities of THM and CON, since they are a joke now. They do next to nothing in dmg and give you about 1-2 MP. Just like they did when game was released.

All in all I'm seriously starting to think SE has lost it. FFXIV will never be anything than a sidenote in their portfolio and a downright embarrassment compared to other MMO's released these days.
Get your act together SE. Now.

Oh and I'm also on the Besaid server. I moved there from another server, because I heard it was a RP-server, and I was curious about what that meant for everyday social experiences. Not allot as far as I can tell. Oh well.
