NO.
Im sorry but NO. If you want to prevent the points you mention, its a waste of time.
In PL as well. ONLY:
A) You roll it behind the scenes.
B) You ONLY roll for spec/roll appropriate items. No more bows in groups with 0 hunters, or mail in an only plate group.
So GL will NOT solve this.
Really? This happens in GL, ML, or whatever system you want. The only way to prevent this is to ban trading all toguether. Which is worse.
GL will NOT solve this. It will make it even worse because people will not only trade stuff, but double need roll for stuff they dont need/wrong spec and trade it anywais.
I am confused how GL will adress this better than what PL does. Like point 2, they will need for items they dont need/cant use and trade them off.
If anything GL makes it even worse.

I beg of you. PLEASE go read the GL complaint posts from raiders. In SL there were hot-heads like you with little memory that forgot WHY PL replaced GL to begin with.
Here: Have a taste of what is coming your way if you insist on this GL BS:
So NO. ABSOLUTELY NO. I wont have this discussion again. Dont ruin the ONLY content I have time to play.
PL stays. With ninja looters and all. PERIOD.
