Been maining bamboozler for months. MK III is really really good and will probably be the best Bamboo option in 85% of situations.
For one you can camp walls now, so the weapon is suddenly viable on Moray. You can reposition easily which is great. And burst bombs fill the role of Disruptor if you throw it then shoot them. Looking at a highly versatile weapon right here. Probably a Top 10 weapon.
As of right now I can't think of a map/mode where it can't perform well. As much as I loved Bamboo before I couldn't even say that. Moray, Urchin, and Ancho-V were all rough on it. Mahi SZ was also rough. But I feel MK III will handle just fine on these maps.
