most people don't understand that it is much easier to bring the outlying things into central than shift everything in the game up to a new par.

for instance they felt warrior was too far below average and bard and apparently summoner(??) were too far above so they made adjustments to bring everything back into the middle ground.

if they instead buffed everything to match the top performing jobs you would have to re-balance every job instead of just a few and then also have to re-balance all the in game content that was meant to work with the classes that were considered standard and under-performing because every class is now over-tuned for all existing content. The work necessary to balance without including nerfs is almost like rebuilding the entire game

I know nerfs feel horrible but you need to realize you were enjoying being better than everyone else for a long time and these are just meant to bring characters back in line.
