I know the kind of anxiety you might be facing and I’m not here to judge, but I do believe the community is way nicer than what you fear it is.
I can only makes assumptions as to what would cause stress in playing with randos, but mistakes happen, failures happen ; and the only advice I can give is communicate. Not only because it will prevent some mistakes, but mostly because it builds some sympathy and people tend to gloss over those mistakes with a smile if you’re not “another anonymous a**hole rando on the internet who happened to suck this once”.
Back on topic, bots are ok until they’re idiots. I don’t mind having to snipe specials cause that’s just what I do, whether I play with bots or players. Elite pinging is also not a priority for me, though tagging specials would be nice when they’re behind a wall of Chaos Warriors for instance.
The things I do prioritize is them standing on your downed body and picking their nose (with a dagger) instead of rezing, and all 3 getting downed by a roger’s slam - which doesn’t happen in ‘perfect’ situations, but does often as soon as variables like other enemies or terrain or a shout displacing the monster come into play.
