there's a difference between "playing with gunboats" and playing in a scrim/match with gunboats (pugs don't really count because no one gives a fuck).
it is also absurd to state that you have a good understanding of the game because there are countless mid im/top open players who have infinitely more experience than you whose understanding of the game could be classified as rudimentary at best. we say you don't have an understanding of the game because you don't.
