Cross-Class - System = Is it Cancer?

[Bourne_Endeavor]

Whm is still useful and has skills the others don't have and others that I've talked to still prefer to have a whm in combination to an ast or a sch for end game content.

A lot of people still prefer Monk. That does not change the fact it is the worst DPS job due to its woefully lack of utility and party synergy. The absurd buffs to Astro made taking White Mage more of a hindrance to endgame content. Can you still clear? Absolutely. I'll take a competent White Mage over a Scholar who has no idea what they are doing. That being said, Astro/Scholar is undeniably a far superior healer comp in the same way Dragoon/Ninja or Dark Knight/Warrior trump their respective counterparts. Three jobs suffer immensely while doing progression. I dare say White Mage has actually replaced Paladin as the least beneficial job, though you could still make a case for Monk.
