Because the thing is, that sentence applies to both sides and it drives me crazy. Most comments about either Classic or Battle for Azeroth end up in mud-slinging matches for no real reason other then one side is being negative about the other side's favorite version of WoW. And the funny thing is, there are way, WAY more commonalities than differences in there, after you remove the ego of "my WoW is/was better yours sucks". In the end, no matter what anyone says, they are talking and arguing and fighting about it because they care about WoW.
Tauren’s hitboxes and their melee reach is slightly larger than other races. Being critically struck while using /sit to sit does not cause abilities like Enrage, Blood Craze, and Reckoning to activate. Using the “Automatic Quest Tracking” option does not auto-track newly accepted quests. (It instead will start to track an existing quest once progress towards an objective is started.) Warrior health Regeneration is working at the expected rate. Quests objectives and points of interests are not tracked on the map or minimap. Completed quests are marked on the minimap with a dot. (and not a “?”) Feared players and NPCs run fast. Standing on top of other players while facing away allows spells and attacks to be used. Creature respawn rates are much slower than in Battle for Azeroth. NPCs which offer multiple quests may inconsistently display them as a dot or a “!” on the available quests list. They were inconsistent in 1.12, and we’ve reproduced the exact inconsistency they had back then. Quests that are too low level for do not show up as a “!” in the game world. Available quests do not display a “!” on the minimap. On level up, the message: “Your skill in Protection increased to 15” was added in 1.12.1, and we’re intending to keep that. We appreciate all of your feedback!
Even though a modern server architecture is used, Classic servers won't have the same features that current World of Warcraft does. There won't be cross-realm servers or Looking For Raid and Dungeon Finder automatic party matchmaking. There are still a lot of questions about how the team will tackle it. This endeavor is being undertaken by an entirely separate team at Blizzard from the one working on World of Warcraft and its next expansion.
Things like Tauren melee reach being bigger, which is something I experienced going away live during Black Temple Illidan progression (at least for that particular encounter), is confusing to players as it's a significant advantage over other races in some instances. No quest tracking is another apparently confusing issue, as many Mankirk's WIfe seekers well know, and there's a whole lot more where that came from:
