It is frustrating but you have to look at it from their point of view also.
Hell I get kicked from climbs all the time now more than ever, sometimes people have groups already set up on discord. The biggest factor to prove your worthiness is to have good actions at the end of a climb and work contantly on getting better gear. You don't need top end amazing gear to do really well. If you have items every 10 or 15 levels with lets say 90+ ee and you're active 95+ % of the climb and clicking and using abilities, anyone will climb with you guaranteed. Don't give up just yet
