It made me laugh how condescending you sound. You obviously haven't taken into consideration that some guilds are severely struggling with recruiting players capable of clearing NiM content. Our guild for instance, cleared Brontes pre-nerf however spent the majority of the time NiM DF was available trying to fill AFK spots and recruit for open positions. This is also what we have spent the majority of the time doing since NiM DP was released. We have had all of 2-3 raid nights in NiM DP since it is so difficult to recruit people. I personally think adding a title to clear in a limited time-frame is a stupid idea for this game, but that isn't the issue here.
Some guilds simply aren't able to clear it in the time-frame due to many other external issues with player absence or open positions and not due to player skill.
