The difficulty of the Incursion is the reason why people are looking for exploits!
This message is for Ubisoft Massive.
So now you wanna punish the exploiters for something that was in the game, but you couldn't find it first. The problem here is so many people actually exploited/glitched, you would punish a huge amount of your player base. The reason why people are looking for new exploits is the difficulty of the Incursion itself.
It's nearly impossible to complete the Incursion with random matchmaking or a random group, because most people don't have 200k DPS and 100K health. The enemies were on lvl 31 on hard on your stream, a few days before the release (https://www.twitch.tv/thedivisiongame/v/58575487). I don't know why you felt like making this much more difficult by increasing the enemy lvl's on hard & challenge on the last minute. You should get some decent testers before you throw something at the player base that would avoid more people from looking for exploits.
Edit: My suggestion is add at least checkpoints to the Incursion.
