There is a practice mode for people to experiment with different moves and combos, but it's also best to experiment first-hand against other players. Once you learn the moves and tricks of the combat mechanics, you can anticipate your next move and other player's moves, as well.
This game has a huge strategy factor, pretty much like any other fighting game, but a bit more vital. You can have a newbie weapon and still be able to defeat players with overpowered weapons, but you just have to improve your skill on basic fighting.
One thing that can turn people off when playing this game is the 'pay to win' factor, but everything will mostly depend on your combat skill.
