This guide got me to transition from N-Zap 89 to the basic Inkbrush, and it suits my semi-aggressive turf coverage tactics. Admittedly I play a little more aggressively, but only when I'm confident my teammates can take advantage of my charge to advance and help secure more turf.
I reckon the Noveau Inkbrush's special and sub are better suited to support in Ranked battles than the basic Inkbrush.
