Depending on your job its always been possible to solo mobs near or at your level, specially at low levels - the question would mainly be: How long does it currently take to solo said mobs? I doubt any of those mobs would be able to kill a healer, paladin or RDM (and maybe to an extend the other tanks) as long as the person playing throws out the occassional healing-spell... so the question is only how long it takes to kill said mob and even more so: How much fun are you having...?

I'd be willing to award them points for doing away with the mount-restriction, hadnt that restriction not been a pretty stupid idea in the first place...
