yes, some ppl prefer to do the sidequests and take there time; and some ppl like the story line so they stick to the story and find themselves going through it pretty quickly. id have to say though, finishing mb at 29 is definetly uncommon. the average for finishing it is 32- 36. so yes, its unnatural, but who cares? LOL
Its Normal. IBeat MB At Lvl 27 And I Did All Side Quests ..
Nice thing about side quests you can do them anytime. I like the idea of being able to go back and easily finish some because I am so high up now that some places are a ball park now and it makes getting rewards much easier when you go back.
