It's because it's only a point of view. And not an universal law. 90% of this post are "X is better, because... and if you give me YOUR arguments, and YOUR point of view, then it's wrong."
And i don't think Wotlk mecanics were better than MoP mecanics, just same problems, different places.
During Wotlk we had :
PvE gear was mandatory. (Caster had too much haste, melee had shadowmourne and arpen)
Bloodlust in arena. (Wizard, LSD, beastcleave...)
Ring of Valor. (With fire at the beginning, DC problem, no LoS)
Mana burn was a thing, even in 3v3.
Tank spec was here. (Mage, do you remember the protwar/mm hunter/hpal?)
Title in 2v2. (During 2 seasons.)
Hybrids and ridiculous spec. (As a paladin, we had the shockadin spec 37/0/34, and the prot-heal)
The OLD Battleground system. (So if you say "The title mean something, let me laugh, title have not meant anything, do you think my 3 title during Wotlk means something? I played feral/shockadin during S5/6, and destro/elem/pal during S8, we killed people during a shadowfury.)
More, more RNG than now. (Winter's chill, holypaladin cleanse which give 30% of "Miss miss miss", all the talent which give you X% chance of dispel resist...).
For me, every new xpac is the same as the old one. Sames problems, differents places.
If you say "X was better", it's ok, but it's just your point of view. For me, the best season was S11, not because of the season nonononono (Haha, hello Gurthalak). But because of peoples i played with, and this patch (4.3) bring me the transmog system.
