As much as it pains me to say this, I have to disagree with those who call it glitching. Gaming is all about putting you in new scenarios. Games like Destiny want you to be robust and find new ways of accomplishing things; this can include use of terrain, general knowledge of how game mechanics stack up either for or against you, etc. A glitch is where someone does something to reach or do something that should not be possible at all in-game, such as those used to explore locked DLC areas like King's Watch and Traitor's Ketch. that is glitching because you are exploiting a minute technical oversight to get a sneak peek at content that is meant to be paid for. I have never seen anyone glitch in Crota, just using what they know about the Raid and how it works. People know that the thralls will despawn on the first side if no one is present, and they know that Warlocks can self revive and that you can use the terrain to traverse the tower on the right. If bungie don't like that then the solutions seem pretty simple to me: change it so the Thralls and Acolytes DONT despawn when that side is clear, add an invisible barrier that stops people from scaling the tower, change the functionality of the sword by increasing how far you drop when swiping in the air. These are easy fixes for problems that they created themselves. If they can't be bothered applying these easy fixes, then they have no right to complain.
