I’m very glad to hear it OP. Reminds me of my first mecha run, and since I’ve always welcomed “new” mecha players into my weekly runs to help them learn and experience this dungeon as it is so fun!
If you like the attitude you got there, non toxic, relaxed, try and try again. Might I recommend you give the Scared of Dungeons community a look? I’ve only been in it around a week but it’s a community set up for mythic+ precisely for players who don’t want the toxic gogogo in their mythic runs and won’t rage if there’s a wipe or key timeout, and rio demands are nowhere to be seen.
Being in the community doesn’t necessitate spamming mythic, but it gives you a means to find players if you do need a group for a dungeon etc. And prefer things to stay positive! It’s how I managed to finally get my first mythic 10 run under my belt despite being unexperienced with beguiling and failing the key timer, giving much needed experience for future runs!
