From what I've seen it's mostly people tunnel visioning. They focus.too much on their own deeps that they ignore mechanics. Stop trying to kill the command tower and hit the sand orb please!

That aside I have no idea how people continue to due from the falling pillars. I only ever got crushed once and that was because I tunneled trying to heal my team. The fight is easy if you do what you're supposed to do.

I once had the mt on my team who decided that it would be a good idea to stand on the completely wrong side of the field when the fire fist came up. He promptly died to the DoT because he didnt bother with a cooldown. It's not even like he tried to save himself. He did this every fire fist.

I do mostly think it's people having tunnel vision though. I've seen a team try to burn Hashmal from 20% as golems were spawned. Yeah that led to a wipe...
