If you are new to this game, you've probably encountered a lot of older players in dungeons who are huge jerks to you, and maybe a few helpful ones. However those players that are jerks to you aren't jerks to you because you're new, it's because you're not listening, or warning people that you are new.

If you are a new player, THEN SPEAK UP! More often then not, a veteran player in the party(if there is one) will explain the dungeon to you, and possibly even give you helpful tips on your class/job. But if you don't say anything, and are constantly screwing up, and making a mess of things, they will get mad. If you take the advice, and then jsut say screw it, IDC gonna do what I want, and mess things up for others, they are going to mad at you.

We're all new to the game at some point, and some of us aren't great players, and some of us are great players. No matter what you're skill level in this game is, WE ALL HAVE TO START SOMEWHERE. You are doing nothing but hurting yourself when you don't let people know that you are new. Asking for help is not a bad thing, it doesn't make you weak, nor does it make you a scrub. Asking for help and alerting others that you are new is a simple courtesy that will take you very far in this game, and will actually help you better yourself.

So please, do yourself a favor, and let others know you are new. Most people have no issue helping those who are new, but it is extremely hard to not be a jerk to new players when they don't speak up or don't listen. Don't let yourself become a victim.
