There will always be people worried about their character or job or class in games that feature big updates. Go to any forum for any game before a big update hits, like this, and I can guarantee you'll see people saying they may as well just delete XXXX. It's just especially bad here because WHMs had felt they were getting the short end of the stick for a while due to the constant (and justified, mostly) buffs AST had been getting for the last 2 years. We felt they overdid it a bit in 3.4 and so were looking to SB for Squenix to dial it down a notch, but instead it looks as though they doubled down.

Is it hyperbolic? Almost certainly. But in amongst the calls for pre-order cancellations and the like there are some valid points.
