I think we've wrapped our heads around these concepts just fine. Not liking something because it fucking blows (for reasons many people have enumerated in every GW2 thread since the game launched) is not the same as not understanding it. I am TOTALLY capable of understanding what it would be like to be anally violated by fucking Pennyworth, while also still deciding I probably don't want that to be a thing. PvE, jumping puzzles aside, was complete trash. Events were mildly interesting once and then painfully transparent every other time (THEY'RE TOTALLY NOT QUESTS! but they are. And less varied. And you have to wait for them to spawn. etc etc). Not a progression based game? the fuck does that even mean? If you're not interested in 'progressing' in GW2 (even if the form of progress presented is prettiest princess vanity progress for transmog) you will exhaust all content the first time you hit 80. Living Story has absolutely nothing for you unless you're super interested in grinding for transmog progress. Counterstrike and DOTA are not progression based games, you play them and have fun and replay them over and over for more fun, GW2 you absolutely play to 'progress' aspects of your character, or you stop playing entirely. There is nothing else compelling enough to do repeatedly.
PvE is different, we know that. It's also awful. Grouping is awful. Dungeons are awful. The lack of trinity is an abject failure.
Basically the entire game is a failure, except for jumping puzzles. Fuck yeah. Jumping is really good, not gonna lie.
