I'm not saying PLD is only overpowered with Aegis. They are getting increasingly powerful without it. However, with it, they are just stupefyingly powerful. (Fafnir hitting for 15-20 damage a swing)
The point isn't even about how powerful PLD has become. It's the fact that SE continues to give so much attention to a job that seems to get something new almost every other update for the past year, while at the same time, there are a ton of jobs that need a LOT more attention that are getting shafted. Jobs like BST and DRG come especially to mind.
Also, to be fair, the other relics aren't downright game breaking like the Aegis is. You give a PLD an Aegis and he is ungodly. You give DRG a Gugnir and he's just another DRG. You give a THF a Mandau... he's still just a Treasure Hunter whore for your drop-rate. The only other relic that is even remotely as big of a deal is the Gjallarhorn.
So now PLD is getting newevery other update AND has the best relic in the game. Now you see my point?
