What did not work as expected? From what I could see it worked exactly as expected, I could switch between two specs and so could others, and people definitely did so.
If you thought it would fix the tank/healer shortage that was a you problem, if you also donât think it helped that is also a you problem.
The problem with the âbring the player not the classâ philosophy was, in order to realize it they had to go down the rabbithole of homogenization (and pruning, eventually). All healers got a magic dispel. All DPS classes got decent AOE. All tanks became able to hold AOE threat. And thus the game lost that special feeling where classes had strengths and weaknesses, but compensated for each other and worked together in a raid setting (or an arena team setting).
Ultimately, classes need to be well designed and fun to play. And then you need to enable people to play them. Dual spec is just an enabler. If class design is terrible, dual spec isnât going to fix the tank shortage. On the flipside, I enjoyed blood DK so much in cataclysm that I switched mains to it, and I tanked stupid amounts dungeons and raids in cataclysm, simply because the class was fun, and the encounters were fun. Many was the random that benefitted from me tanking a dungeon. And dual spec let me do it whenever.
It literally doesnât affect that though. Whatâs the difference between clicking a trainer and paying 50g to respec, versus activating your secondary spec?
The same problems were there but I also found the game more generic and less fun. The loot system became a boring meaningless token grind from meaningless dungeon crawls with strangers. Dailies and more dailies and then a characterless workmanlike raid called ToC.
Ulduar was good and icecrown okay but generally speaking I had less fun in WoTLK and felt it was more of a chore than any other iteration of the game Iâve played. I quit and came back a couple of times through wrath.
The design model failed as far as I am concerned.
Obviously many others donât agree, theyâre welcome to play WoTLK classic when it comes. But for me it promised sooo much but in reality was easily the weakest and least engaging of the three early wow games. So, no - âletâs transpose X WoTLK feature onto TBC classicâ does not excite me. Iâm open to change but donât view WoTLK as an improvement.
