Where to start...
  • 1.23 combat and looking forward to the revised Battle Regimen/Skillchain system that was going to be implemented.
  • Crafting that was actually useful outside of making fluff items.
  • Breaking down fish and clusters into crystals and shards instead of farming for them (why was this removed again?)
  • All of the old animations, sounds, and music. The inertia, Twilight Over Thanalan, Steel Cyclone, Spirits Within, voices, etc.
  • Coerthas (surprise!) and all of the potential it had. See: http://www.youtube.com/watch?v=LpmsFVCaKP4
  • Unique traits on armor and weapons.

What I really miss is reading all of the old updates for 2.0 when 1.0 was still running and imagining how awesome it was going to be. Now that I'm here, I doubt whether or not I'll be able to stick around for the long haul.

Yoshi-P has said that he hopes 2.0 will be around for at least a decade. However, if I only have more instanced dungeons, bland armor upgrades with only +5 more DEX/STR/VIT on it, and lame dodge mechanics to look forward to for the next ten years...then I'm done.
