I think the problem is the game tried to be all things to everyone which is impossible so parts came off as mediocre at best. For instance I couldn't care less if they took the crucible completely out and had a much more involved story with side missions to expand lore and background instead of dumping it all in a grimoire no one will bother to read. Others I'm sure don't give a flip about the story and wish all focus was on pvp. You can't give everyone what they want. Skyrim rules story, CoD/halo rule pvp, WoW/GTA5 rule social interaction. No way can this game try to do all three at the same time and even approach the standards set by these games. They tried and the result is mediocrity, playable and sometimes enjoyable mediocrity but mediocrity none the less.
