Blizzard had to make the BoP orbs for crafting only needable by people with crafting professions, it was a large enough problem that they had to patch it. They had to introduce personal loot to make sure people weren't ninja-ing gear. They had to make BoE items becomes BoP if they were needed on, because people were needing to sell. Those are just some examples to prevent bad player behavior on WoW.
Making these changes is normal for an MMORPG. If anything, Blizzard has more of a need to fix these problems than SE does, and the fact that you actually believe the playerbase on WoW is better than FFXIV absolutely blows my (and apparently everybody else's as well) mind.
