Been at it for 7 hours now. I don't get it.

Mostly just running around with giant zergs of people for 30 minute stretches until you finally get somewhere and then you get killed by an NPC and you get to run back for 30 more minutes.

I'm not gaining any XP doing this, so there is no character progression.

There has been 0 skill-based small skirmishes where I felt i had an actual impact.

Just follow, zerg, set up a siege weapon and shoot at a wall until you die and then go for another very long run.

I'm just not digging it.
