Honestly I am not sure what was particularly hard. I came on an undergeared alt, ran around for about an hour and got almost fully geared up without killing a single mob. If you are fighting mobs and are way undergeared, sure it is going to be hard, but that isn't particularly unique to the isle. Most of the rares are dead easy. There are some mobs like the gulp frogs that you do have to be careful of, but here is the thing there are plenty of easy mobs to kill that offer the same rewards, there isn't much of a reason to screw around with mobs like the gulp frogs. Generally the harder mobs with better drops are going to have a group killing them anyway so chances of getting killed then aren't particularly high.
