No game can please everyone so I understand some of your complaints, but I think a few of them need a little more attention.
You said zone clears are the only thing to do in PVE and also mentioned how combat was boring against normal mobs, but never mentioned dungeons! Dungeons are the meat-and-potatoes of the difficult PVE content that actually makes you use your skills.
As for armor smithing, loads of people are doing crafting wrong so maybe the game should explain it more. If you make the same thing more than once you are screwing yourself out of loads of EXP. Crafting gives huge bonuses for discovering recipes in the exploration panel. I'm at 120 armor smithing and I still have tons of ore for weaponsmithing too. Its those claws and blood ingredients I find hard to come by, need more insignias!
Are you playing WvWvW with a guild or some friends? An organized group takes a keep very quickly, and organized teams is really the highlight of the game type. Small groups are better suited to taking supply camps or towers. Don't forget about the PVE built into to wvwvw either, you can recruit local mobs to help your server if you feel useless going back and forth in the big battles. I think this gametype will only get better and better as people hit 80 and a match finally lasts long enough to upgrage some keeps!
Glad you are having fun, hopefully my post can help you have even more fun!
