In earlier titles such as Skyrim&Oblivion quests were used mainly for rewards and unique weaponry...will they still continue to do the same setup in online or will they go for a more RPG approach with experience points towards your next level? Technically all ES titles did this considering the barrage of enemies you kill during...but curious none the less...

It's an MMO, I'm sure quests will give you EXP.

The reason many games give you xp for quests is to incentivize powerlevelers to actually play through the story instead of just mindlessly killing the same mobs over and over.

However, I don't think it's obvious that ESO will go that route. Since a powerleveler may not WANT to play through the story, why not let them do their own (tedious) thing? Not written in stone that ESO will make that choice. In any case, seems completing some questlines will be necessary to unlock the next area, so that may be enough of an incentive.

MMOs don't all do everything exactly the same

That's exactly why I felt exp points were needed actually...I enjoy being rewarded for completing tasks in most rpg's...but ES games have such entertaining quest lines that its not much of a bother to me...

Exactly, why force a player to do quests over mob killing, if the story is worth it, players will want to do it. However most quests are boring unoriginal time sinks, and even when forced to accept for XP, its just button clicking not reading so i can get back to the killing.

It seems dull to mindlessly travel around Skyrim or Oblivion just killing mobs though...besides going into caves and such and finding great equipment at the end, that's always fun...

I see no logic in that. They seem to be following the skill usage system in order for the player to level up, the last time I looked. I would be somewhat illogical that you level those skills up by completing quests unless the quest giver gives you some training as a thank you.

In games where you have a limited amount of experience given such as Vampire: The Masquerade - Bloodlines there is somewhat of a push for you to do every single quest in order to become as proficient as possible, as a result there deters the player from turning down the quest giver regardless of whether they like them, wanna play a rebellious character which pretty much gives people the middle finger if when they talk down to you? You can do that, but you'll be at a disadvantage the more you progress through the game with that type of characteristic.
