It depends on the server. Some servers don’t view helping others as a bad thing vs others who are willing to get know you and help you out.
I would say before you settle on a server take some time and check each’s community out if you are settled on playing classic. Look for guilds with the same mindset as you. But also keep in mind that cliques are something that will be out there and aren’t nessarily easy to avoid. The classic version of the game more supports that style of community over retail. People can have more control over their community here and that isn’t always a good thing.
Not everyone is like that. There are good people in this game who look out for eachother and try to help one another and will do content outside of end game still.
