For a start, the best is to focus on only one class, no hybrid, otherwise you will lose important skill point usefull for melee.
I think the best to start is 1h shield, so you can focus on counter attack without having to mind too much about blocking. Then you can switch to 2h or polearm.
Then to have some fun while learning fast, the best is to join a clan so you can speak with someone while duelling and he can give you advice during the duel. And as you look like someone cool, you should have no trouble finding a clan.
When on EU1, you should try to learn teamplay as much as individual skill. Teamplay is a lot more of fun imo and you can quickly get good at it. For exemple try to protect your teammate from enemy hits, see where you should place yourself to easily land hit on the enmy and not bother your mate,etc.
