I'm not sure what else you may have been looking for in terms of answers. It is important to note that trains happen and you will die (sometimes a few times on a given day). It's part of the fun in a way. For example, Unrest is fairly train prone. Fighting stuff in the Main Room or Fireplace could be challenging as it is but add in the occasional train and that moment when you all need to haul it out to the zone line and it adds some excitement to the game. The best times I have had in game were in places where death was always lurking around the corner.. The dullest times were spent grinding XP in relative absolute safety (Overthere, Oasis, etc). It was fun going deep into SolA with a group a few weeks ago. We always kept the nearest exits in mind (and had to use them a few times) and had a great time exploring. The battles where people almost die or the party almost wipes were exhilarating to survive.
Once you get enough levels under your belt, head to Befallen, Guk or Unrest or Najena (Najena however is a bring your own group place though as is Befallen but it's easy to pull people together). It's great fun fighting in these zones. Great XP and some nice loot at times. You could also head to Kunark and hit Kurn's tower.
