Yes it completely destroyed class design for many classes (cos of pruning), you had to farm ap 24/7 at start, rng legendaries at start, no character customisation in pvp, overall it was not alt friendly, the best thing about it are probably visuals and addition of m+. Overall it has many flaws.
What does this mean even? Do you think people would never swap games just cos its different genre or? Wow hype ended with moba hype. Lol is even free, more competitive, more balanced with more patch notes than wow. Check how many new people play wow btw and how old people playing this game are and then compare it to lol. Wow (especially classic) doesnt attract new people cos it simply can’t compete with games that are popular today (and were popular even in 2010)
Thats exactly what i’m doing. Playing superior expansion compared to wrath/tbc/legion with superior class design, better leveling, more balanced pvp with better raids (not better than Legion tho), basically better in every aspect.
