None of that has anything to do with light level....or experience. It has everything to so with poor team balance. Poor team coordination...and people who are too impatient to allow for people TO LEARN these various roles. But then those people are usually the first to complain when they can't find people who know how to do them. The teams that wipe are because you have players that don't make call outs. The teams that wipe are because someone's TIMING is off. The teams that wipe are because someone is playing while they're drunk or they're HIGH...and they can't keep from -blam!-ING DYING every five minutes. The teams that wipe are teams that are being poorly led...so no one is entirely clear on what strategy is being run., The teams that wipe are the teams where people get panicky or easily frustrated, and they start wanting to change the strategy in the middle of the fight and it unravels. Teams don't wipe at this point because of a lack of players that know the fight mechanics. They wipe because they are either being poorly led....or are working TOGETHER poorly. If you're still learning the mechanics of these fights after seven completions? There's something wrong. They are NOT that difficult or that complicated.
