The raid is amazing fun.. Just be prepared to die and start checkpoints over again. Just take it easy if you have a group of friends who you will do it regularly with, I recommend going in without a guide the first time to see what it was like when the first people attempted it .. Then go find a guide to get you through quicker and before long one if you will be the natural raid leader. Night fall is probably harder strategy wise because it's different every weak so you cannot get used to it. But the raid take more team work and co-ordination but it's easier to form strategy.
