Well I think its pretty obvious what the overwhelming majority thinks. (Keep in mind this poll has been open for quite a while and ''easier to find them'' has never dropped below 60%).
I really think bosses should have a chance to drop items and access to them should be wayyy less grindy.

Wether the solution is to raise droprate of marks without changing drop locations and reducing the boss drop accordingly or moving the mark drop to tougher areas is up in the air (both are same tbh).
