Combat is too repetitive.

Randomness in patterns makes a battle or an encounter a game of luck, if boss's moves are weakened, it makes the encounter easier, pattern recognition is crucial to avoid 1 hits but if 1 hits no longer poses a threat, I might as well just stand there and tank every thing making all encounters like T2 Enrage. The only way combat can be made "alive" is if the game has a highly advanced AI that responds to player's skills and movements and evolve to develop strategies to deceive and defeat the player.

Elemental wheel doesn't add "fun" it simply adds the same repetitive combat you're talking about and there will be difficulties balancing damage output, if BLM are the only ones capable of delivering elemental attacks to exploit elemental weaknesses, we might as well just have 4X BLM instead!

Its not as easy as you think it is and for the record, I have yet to come across a MMO with highly advanced combat AI that evolves and makes enemies feel "alive"
