Kicked for exceeding damage

[The Original Fiend]

Well this pretty much confirms that you dont get kicked for exceeding a certain amount of damge and makes me pretty certain that the problem is the nebula armour dropping the buffs. In this Im only in solar gear with tanking items

Wrong. Exceeding the amount of damage in one shot, which is at least over a thousand. The highest one on that screenshot looks like its 686. You can easily exceed 1000 damage with a sniper btw (critical).
