It's the informal version of regardless, would you have preferred me to use that word? I didn't know this was an English grammar forum where polysyllabic words made a post more relevant. My apologies to you, kind sir. However, now I feel like I must make amends for my transgression to you. K/D does not matter in a game, when it simply does not make any difference to your rewards based on the level, or lack thereof, of your skill and/or performance. Better?

Sure 👍
