First of all in my opinion this is not a Glitch.
Here is why,
[b]Atheon freezing:[/b]
Atheon does not freeze because you take him over to some special part of the map. He freezes every time he opens the time conflux “Teleporting the people in the back into the right or left portal”. This is by design, he will freeze anywhere he is standing at the time he decides to open the time conflux and teleport.
[b]Falling off the Edge:[/b]
You can literally knock any enemy of the edge as long as they are close enough. This is not a glitch but again a game design. We can also die from falling off ledges.
[b]People just found another way to beat the boss.[/b] Is it quicker? That depends on your team.. Just like doing it the DPS grind way. People can still not get through the portal and you have to wipe over and over. He can freeze in an in opportune spot and you have to wait for the next time conflux to reposition him.
[b]Should Bungie Patch it? [/b]That’s really up to bungie. However, I do agree with the other issues that should be fixed along with it. Warping only two, Splash damage issues, etc..
Feel free to comment. Positive or Negative does not matter.
