Making GW2 like GW won't earn them respect any more than them saying outright, "We ♥♥♥♥ed up," although both actions send the same message.
There is very much in between being exactly like the prequel and being nothing like the prequel. Most of us didn't necessarily want gw2 to be exactly like gw1 (I personally wouldn't have mind expansions instead of gw2 though, regardless of how gw2 could have been). But you shouldn't make a sequel that has nothing to do with the prequel except for some lore connections. But apparently this is not true anymore (I look at you diablo 3).
