I agree with you on a lot of this. I want to just add my 2 copper on a couple points:
-Timeless Isle- Love everything about it except for the rep grind. I was happy to leave that kind of grind in Silithus where it belongs! An extra daily or even some turn ins would have been nice, I just hit honored on my main after spending an hour AOE farming the Yaungols.
-Rep Grind- It was a little ridiculous and alt-barring. Though when I finally got my 1 alt to 90 2 months ago, Cloud Serpents took 2 days with all the eggs that were left up! Yay me!
-Linear Raids- I liked how Naxx was set up in wings of 3-4 bosses that were in and of themselves linear, it was nice to be able to pick which wing to do next and have all 4 complete to move on to Frost Wyrm Lair. Ulduar did it fairly well as well. Overall I enjoyed MoP raids, but I only did non-LFR in MSV and SoO. Had to take a break after the guild I was in at the beginning fell apart.
-Tillers- Overall it's great, though I wish you didn't have to grow the portals and take up precious farm space for a port to Silvermoon which would just get deleted. A single port in the farm house with a dialogue box to choose which city would be fine. Just make the grind to own the farm a little harder to get, IMO. However, this brings up a point about cooking. Raid food is best in MoP if you cook your own and bring it. You can't get the stamina from Spring Rolls from a noodle cart or a feast. Now, that doesn't effect me, I bring my own food and flasks always. But my guild provides for its lazy ass members too, and they're never made to have to bring the better food. That irritates me, but I guess it's more their fault than Blizz's, trying to force people to do better.
-Professions- Utter failure. I'm not into learning random patterns for doing daily stuff. Give me my choice of which one to learn daily if you want to gate me, but making it random so my warrior is getting int/spirit/haste gem patterns before crit/str/stam/avoidance is just crap. The bonuses to raiders are pretty stale at this point too. I think it could use a second look. Also, as a JC who's now facing a failing gem market, F YOU FOR NOT PUTTING EPIC GEMS IN, BLIZZ.
-Legendary- I agree with you on this. Interested to see what they'll do for legendaries in the next expansion! The cloak was my first ever (still waiting for the 2nd binding to drop, with 10 elementium bars in my bag).
-LFR Loot- Meh. I hate the LFR system as a whole. Glad to be doing normals again so I don't feel obligated to sit through that trash.
Again, excited for the next adventure, wherever that may be.
