Whole idea of expansion was already full crap. Alternate fucking universe...
But i'd say my biggest gripe is still the raid-or-die-mentality. Most of the non-raid content (actually everything for me) was just pointless and/or boring. And i don't like raiding anyway so...
Shipyard also gets award for stupid design. What the actual fuck, which navy would operate on the basis of "let's send ships on suicide missions and just build new ones after that"? What the hell... I will rage so hard if legion's follower missions follow that kind of RNG shit. I would have been ok with it if instead of sinking, ships would come back to harbor broken and without half of the crew (so you would repair them and recruit new crew), but no, lets build new one from the lottery rng machine...
Actually shipyard would be shining turd diamond on top of WoD. Culmination of retarded design. I have only one shipyard (on my main, i don't even build it for alts, tanaan also is really boring grind valley so i won't take my alts there) and if i can't get over 90% success chance, i simply won't do the mission.
