IMO followers are an iffy choice. The couple times I used them they were a bit frustrating 'cos they tended to rush in ahead of me and I couldn't get a clear shot with my bow. (I sneak/kill a lot). Even in melee they were in my face. Besides, they don't seem to be able to bring down a mob very quickly either. Otherwise they make good mules. Just my 2c.
Playing on expert, I've given Jordis the Sword-Maiden a full suit of legendary Daedric, an enchanted legendary Daedric sword and a legendary ebony shield. If all I do is Dragonrend Shout an Elder Dragon, she'll kill it within two minutes and lose less than a third of her health. She is TOUGH.
The difference is that this game the collect 10 of whatever are optional unlike WOW you can stick to the story quests. And i skipped alot of the kill 10 of this quests.
You'll be a bit underleveled if you continue skipping all of the quests. The nice thing is that the voice acting gives it context and motivates me as the player to get it done. Simply having a decent reason WHY I should do something makes it that much easier to suffer through.
