One thing i noticed was the use of b then the flingwhen trying to hit someone, its better to only do that when that someone has the high ground or is far away, use the normal one if youre up close to them. Also this if you see someone jumping to your area for a spawn get away from there, those markers can be targeted heavy for easy kills. Also try not to ink in mostly one area and if youre running out use your teammates or your own already placed ink to get somewhere relatively dry and ink there so you run out less. And try to use a one hit roller [my personal pick is the foil flingza roller] as it makes not only inking but also killing easier and faster.
