Welcome to the Veteran club !!!
Sad to say but you have only done 30% of the game and now you need to adjust your spec and playstyle to match the heroic version of the lowby zones from the other factions.
Hope you can get trough it as many others have failed to reach the V10 cap before rage quiting.
Pro tip - do all Dolmans / Public Dungeons / World bosses / Main Quests / or you end up running dry real fast...and you come short on exp to gain a level.
Dont bother mob farming ! after 6 hours your exp barely moved up.
Try doing some pvp if you dig it to break the mindless questing that can get to your head and makes you "ugh i dont want to log in anymore and do quest syndrome"
Try to enjoy the 'ride" i mean grind to V10
