Some guilds/players like figuring out tactics (including TL stuff), some guilds/players enjoy more the execution : progressions raids are not only theorycrafting and wiping until a proper tactic and all the mechanisms are known. Again, i've never felt that my satisfaction could be somewhat gimped cause tactics (not even complete, as it seems) were released by QQ and later TFB. Maybe some have thoses feelings, but they're already part of guilds that clear the content on day 1 or even before. So why bother ?
