I was very active on both forums, and I use both arguments. Not to mention, every thread on aeria is still archived.
It's arguable that it takes "years" to become a good gunner. The system rewards you for hitting an area that the opponent isn't actually in. Not to mention, shotguns are purely RNG.
It's silly to even argue.
Edit: I will be back later to mediate discussion again! In the mean time, please do not troll each other and express your opinions in a mature fashion, or you will be reported once I return (I will not take pity on those of whom paid money so they couldn't get banned for being trolls)
