You see it's not just your gear. There's a learning curve. My first few AK WP runs I didn't complete because I sucked and didn't know how to play! <--- See how easy that was!
But I did these runs among friends so no big deal right.
Then I learned to do the runs and ventured out into the Premade or DF world and all was gravy until I tried a different job. I got the same... "Learn to play idiot!" "Uninstall" "Leave"...
There are 2 reasons for this:
1.) I sucked and didn't know how to play my new job! <---- You see how easy that was again?
2.) A lot of the new community is full of douchebaggery that finds being toxic is more valuable than lending a helping hand.
Bottom line: First admit to yourself that you have some things to learn to improve your game. Second accept the fact that you're going to deal with douchebaggery unless you play among friends only.
My solution was to come here to the forums and rather than complain about the douchebaggery that will never go away no matter what you post... I asked for some tips and got better at the job I was playing horribly.
Now I speed run like a boss, and you will too someday my friend! So in the nicest way I can put it. Keep your head up. Keep gearing up and learn to play your job to it's limits. It's the only way to escape the toxic chat.
Or there's always the other option. Take their advice and don't play. It's your choice, but right or wrong... the toxic players will not go away.
