Very yes and no to a lot of these topics.
For post #1, I think some areas you've discussed have some merit. But a lot of what you're suggesting is a little ridiculous.
Some class names I do agree need to be changed, such as:
Gladiator: A tanking class with sword and board is a defender, a paladin, etc. Not a 'gladiator'
Lancer: is acceptable due to the removal of the wyvern aspect.
Archer/Ranger: works for me as well. Pugilist/Monk either way doesn't bother me.
Thaumaturge: wtf is a thaumaturge? It's a friggin Red Mage
Maurader: No issues
Conjurer: as an entire class is kind of messed up to me. It seems to play more like Scholar than anything else in a way. But both white and black magic have been combined. I understand that it makes a healing class more 'solo-able', but for people that want to fill Dps roles in parties, and 'not' main heal, it leaves us stuck. Combining the two was a bad choice in my opinion. I agree with Alicia_WM about the different weapon choices to split the jobs.
