I understand this feeling 100%.

When I first started playing with some forum friends a few of the first players I encountered were so far beyond my level it was incredibly intimidating to play in front of them. I am still insecure about playing AST in front of Miste and the mere thought of going BRD in front of HyoMin is enough to make me want to just turn the game off.

I think something that has made me feel a bit more comfortable is just putting myself out there. Right now may not play AST with Miste but I have healed o5 and o6 with her. I've DPSed in a Byakko party with Cass around. Am I getting purple in these things? No, of course not. I'm still considerably less skilled than they are. They're never anything but supoortive though!

If you're refering at least in part to the little group that some of us have formed there is no reason to feel insecure around them - there is no one in that discord that wouldn't support you trying a new class, screwing up a bunch and asking for help and a big portion of that is just that you are willing to ask for help and accept criticism/cretique.

I know that nothing anyone says is going to make you believe in yourself and I know that because even with encouragement from everyone around me I still think I'm trash 98% of the time but just know that your desire to improve and your ability to see your own faults make you a better player than many others <3
