as of right now, no. Theres basically no progression so just play until you get bored of the 3 game modes.
What do you mean, no progression? There's a lot of progression customization wise. Doesn't take long to unlock all the weapons, though. It doesn't feel as "deep" as Warband though with all its modes and huge maps.
also from what I'm getting here, it's probably impossible to fight more than 1 player that isn't a complete chump at a time?
More or less, 1vX is extremely hard in this game due to multitude of factors. The only two saving graces are 1) bladed weapon slashes go through people, so you can slash multiple people at the same time and 2) having the perk that gives you full health when you kill someone. Still, with a timed block, and people being able to sprint while they attack, you're not going to be winning against decent players.
