Top 5
1.Durnhold – I haven’t run this very much, but I found it to be fun with a well thought out story line.
2.Ramps – it’s tough as a new 58-60 group, but gets easier very quickly. It provides a surmountable challenge, for that reason I like it.
3.BRD – the size of it makes this place epic. There is so much going on in it.
4.VH – easy to run and convenient to get to.
5.Gundrak – Interesting bosses, nice layout.

Bottom 5
1.Occulus – still haven’t finished this one. I hate the vehicle combat. It’s laggy and poorly implemented.
2.Gnomer – I never liked this place. Not sure why, but it’s just not fun for me. I think the whole aspect of a race’s home city being over-run is interesting, but not when you have skull-level faction bosses living within spitting distance. Take it back already! I can suspend disbelief for only so long.
3.RFD – nothing special about it. It has no flair or interest.
4.BRD – it’s size. It’s a blessing and a curse. I still have not successfully run this place at the appropriate level. The reason is the corpse run if you die near the end. It’s too f’ing long! It needs to be split up like SM into wings where you can easily port into one.
5.COS – I don’t like the ever respawning skeletons. That’s my only real complaint.

In general, I don’t hate or love any of the instances. They all have faults and blessings. I tried to think of the ones I run most/least and why.
