We need an ilvl/gear requirement for leveling dungeons

[TheForce]

That's not what it is about. But getting to 80 on multiple jobs without knowing absolutely basic things like:
yes, there are vendors who sell level appropriate white gear.
Yes, there is the market board where you can grab some HQ stuff cheaper than vendor non HQ because people leveled their crafters.
Yes, there are tomestone vendors who sell gear which will last several levels.
Not to mention equipping something for every goddamn slot you have.

Nobody needs to be skilled to know these things. Not by a long shot. It's basic knowledge.

I think you misunderstood me. I'm not in any way trying to say that this player was in the right, what I said was in response the original post. After telling us about how this guy was sorely undergeared, they followed up by explaining how this person had multiple class at 80, as if that should've ensured that they would be immune to something like this.
