But wait! There's more! You can't spam the bambi for coverage, but if you fully chare each shot it gets some good coverage. Plus you can fire 2 or 3 charged shots per second, so it isn't a major drawback.The bambi (i really love that name) is pretty proficient at splatting actually and isn't really all that good at inking turf because of it's really thin inkspread. But i highly agree with the point you're making.
Also, coverage vs. kills would be a large area of debate, and each weapon does it differently. The inkbrush is actually really good, at turf war. Don't use it ranked, its purpose is to cover every square inch of the map. If you use it to cover the entire base, you can almost always win, with 1000 points too!
I guess I'll be done now…
