One, questing is a faster way of gaining experience and therefore leveling up.
Two, repair bills are reputed to be high and the loot gained from the instance is unlikely to cover it.
Three, with prior knowledge of just how difficult PUGs can be in current MMOs, with groups breaking up, people arguing, people not listening to the tactics. I didn't want to go through the hassle of doing any PUGing in a game that, can be, as challenging as Wildstar is. The preciseness needed in boss fights and even sometimes just random in mobs, I could see would make this a challenge for PUGs. I did not want to queue for an hour only for the group to break up in the first ten minutes or to end up in the middle of a shouting match as one member yells "Noob" at another.
Anyway, I elected to make the decision to save adventures/ dungeons until I hit level 50 and until I could do them as a guild group. That day finally came on Friday, and it was really quite enjoyable. There were a few issues, as I had never done even the non veteran versions and it seems my mentioning this at the start was not noticed by the group, as they didn't bother to explain the tactics, but I managed to keep up by just following along. We did three of the four adventures and gained two golds and one silver. Yes, the silver was my fault. But still not a bad result for someone who had never done adventures before. I died about three or four times in total, which wasn't a bad result across the three adventures.
I confess that starting with War of the Wilds which feels very battlegroundy even though it is PvE. I wasn't immediately sold on the adventures but the other two were less tedious and more event/ scenario based and I did still enjoy all three. Although, War of the Wilds did feel a little aimless in places.
The guys in my team were great and I really do thank them, as I have no doubt they, in part, did carry me as I was unaware of the tactics, although the general tactics of stay out of the red stuff, generally does me well. They were on teamspeak, so I followed their directions when given and I think, even if adventures are much easier than dungeons that we wouldn't have got the two golds if I hadn't been contributing at least a little.
Anyway, it was enjoyable and I loved the experience. I encourage others to give it a try.
