Just started playing again with a lvl 90. Should I even worry about farming flying at this point?

How bad of a grind is it to get?

if you do it while leveling it won't seem near as bad as hitting 100 and then going to farm like 40 more treasures because you didn't bother to just pick them up while you leveled.. end up doing a bunch of back tracking and really end up wasting a lot more time if you don't do them now.
I forget the other requirements but that one was the worst..
well and then going to tanaan to get rep. if you have gold buy them rep tokens if not just make sure you complete the one daily to gather 10 corrupted apexis crystals.. I didn't the first few days so ended up having my other 2 reps maxed about 3 days before that one.

it now only requires one rep to be maxed

If this is true I will sue blizzard and any my money and time of my life back.

Game is shit and every time it gets even more shitter...

flying is pointless at this point imo. just grind gold and get your toons to level 100 you want to play next xpac! my 2c

I can level a whole new server to 100 by the time this expansion finally comes out.....

Well lucky you..

I can't because I'm already at max characters per account.

if u just pvp flying is useless

i'm incorrect on this. All 3 tanaan factions need to be revered.
