Wow has changed a lot, some changes are for better experience, some let people down, some make people AFK. Let's talk about things better to keep. Firstly, 40 Raid, I prefer being with a larger team while raiding. It gives more intensive epic feeling. I don't mind competition between same professions, instead of that I perceive 40 Raid makes a guild more like a family rather than a company which people don't have any personal communications. Secondly, I want H-model to be totally removed from sight. As long as it exists, it classifies people and isolates them. I know H-model is just an alternative way to solve a problem which Blizzard don't design enough Raids. This situation is getting worse because people get used to play a Raid with four different levels but same bosses with same repeated plots. Raid is not only a place for people to get gear, more importantly a real content contributed to game. I dislike 10raid being same with 25raids in which I find Blizzard lazy about content design. Lastly I suppose players are too easy to level up nowadays due to reduction in experiences and experiences bonus gear. This setting has destroyed most of the fun that Blizzard used to delicately design for players. See how old world map deserted and forsaken, it surely cuts game into pieces and announce all those parts have nothing to do with each other.
I know people say, "it's a strong opinion, it's based on nothing but subjective complains" Nevertheless, think about true fun of a game, one principle is "more people, more involvement and no class."
