They’re there to point you towards areas with dynamic events (the real meat of the game) and provide you with a quick objective that results in rewards + a new karma vendor.
They’re also a little bit more varied than just “kill things”; usually there are multiple ways of filling that bar.
Having said that, if you’re not enjoying the combat and/or the exploration, then you probably won’t ever enjoy the game.
Mark, I’ve never played another MMO where I had several events chain into each other and take me halfway across the zone, with something different happening on failure. The problem is failure is rare at the moment with a critical mass of players, so we’re only seeing one branch.
For example, in the zone I’m in at the moment, there’s a lake which spawned an event to collect Dwarven Artifacts for an innkeeper nearby. After collecting these, he ran off to his inn. I followed him.
He then had a conversation with a Charr about the artifacts, with some background lore inserted in, and discovers one of them is a summoning stone.
A pirate captain turns up, demands the return of the artifacts, then launches several waves of pirate attacks against the inn. We fight them off, and the innkeeper decides the artifacts need to be taken to a nearby outpost, so he grabs some Asura dudes (who have some funny lines as they’re skint after blowing up their lab) and an escort mission spawns.
The escort mission takes us to the next “heart area” and involves several different types of beasts attacking us en masse. It doesn’t take too long and we get to the new outpost.
Another conversation. One of the Asura points out it’s a summoning stone and that the recipient needs to be very careful when destroying it, so he gets roped in to help out, and they all run off outside the outpost to do it. Apparently the great plan involves releasing the summon, who turns out to be a really hard bastard Champion demon of some kind, drawing in players from all over the place to put down.
I could’ve just done the first event and moved on - there were plenty of other things to attract my attention. But this level of detail is fantastic, and I’ve seen nothing like it in other MMOs.
