Since there is still time for me to work on this and I have nothing to do, I'll go ahead and list what I main in games and why. Don't expect this page to be complete or too neat.
I main Jhin because crits are fun, as well as speed and the ability to damage people at long range Plus, High Noon Jhin has the best sound effects in the game.
Unless the enemies bought, I will buy shotguns because I'm fond of them, I like the look of them, and the potential for making a profit killing enemy players using some "trash-tier" guns is pleasing. Also all the SMGs are unreliable for me to use, don't ever count on me buying them unless we really need range.
I use to main Limbo, but then they reworked him and made him even more anti-team however fun it may be, so I switched to Volt since he's one of the best all-around frames; good health and armor, great crowd-controlling abilities, and good combat capability thanks to his Speed and Shield.
