Well it depends. At the moment there are still FATEs, Leves (Battlecraft ones), Guildhests, Hunting logs for individual classes, Dungeons, Events when they are run, Good ol' fashion random monster killing and Quests that you may have missed by mistake. Personally i like all this stuff, cause while i love questing sometimes i just like to get lost in a world and do this kind of stuff, but i can see and understand how you may feel its a bit slower or boring however. If you want more id say wait until patch 2.1, form the looks of things theres gunna be heaps of stuff added and some more quests too which may help you out.
