1) Why would you want to rework cockatrice's and banshee's droptable?
They both drop tons of useful supplies and overall have a great droptable. I also disagree with Emps Loover, since these two are killed very often.
You guys are right about Monks of Zamorak, they're not killed at all. I'd like their wine drops buffed and the overall table reworked. I'm fine with them being in multi-area though.
2) This has been suggested earlier, but the answer is still definite no.
3) Since the ironman update we could technically add those icons, but I wouldn't like that. A exclusive cosmetic would be a better idea, but I don't see the necessity of it.
