Why do Archers suck so bad against Ifrit?

[Frein]

Don't "adjust balance" by nerfing Lancer. Adjust it by buffing those who need it.

And then when you overdo one class, you again buff everyone else to even it out? Can you say "power creep"?

It's a lie that nerfs are always a bad way to balance a game simply because players feel bad when their class is weakened (class balance is relative, so it's just an illusion anyway). Following a no-nerf policy will lead to characters slowly but uncontrollably growing more and more powerful.
