I'm really good at the Mass Effect 3 multiplayer. It took me nearly 900 games to get the Giant Shepard Head banner by completing the sub-challenges, which are composed of X waves/extractions with Y character, P points using Q gun/ability, etc. There are a lot of characters and guns... to finish the banner challenge, you don't need to use all of them, just 80% or so. But in the process of getting that 80% you learn to either become very patient or you get angry at the grind and get gud at 80% of the characters. So by gud I mean versatile. Anyways I took a break from it the last two years to focus on other things. But I'm back now... mostly because I'm waiting for Cyberpunk 2077 and I don't feel like trying something new. Been completing the challenges again to break out of my rut, and I've rediscovered a lot of characters I hadn't thought to play because I wasn't good enough to make them profitable on Gold difficulty (by minimizing the consumables used during "oh shit" moments). It pleases me.
