Hey there,
Welcome to Regias. I'm sure you'll be able to meet a lot of interesting people around here.
As for your 'concerns' stated in your reason to join Regias, i just have to say that there is no need to worry about them. First of all, it is only natural to be new to a game that is just being released, so dont sweat it and take your time to learn the game.
Also, about your 'not being a hardcore player' concern, just by taking a look around our forum or even our recruitment threads, it is obvious that we are a casual guild with a 'Real life first' policy. So, there is no need to worry about that and instead just focus on enjoying the game.
