This is sorta a guide/idea, even though it is said in the update information I think it will work good.
In the update they say they base their calculators on numerous things but I want to point out a few particularly.
If you die a lot, and then get a kill, your reward is better
If you risk 25k+ f2p or 75K= p2p your reward is better
If you spend a long time in the combat zone your reward is better.
Here is the thing, for the first 20 minutes just commit suicide, with no items outside lumby like 30 times. This brings your reward on your next kills way up.
Then, with a friend or another one of your account is risking the required amount and staying outside of a bank for more than 30 minutes.
You then start to get massive drops killing your friend/other acc even though he isnt risking anything, your just way up their on their calculators.
I was doing it on a f2p mage pure and killed my other account 10 times. After this test I got a total of 8 r2h's, only risking 25k+ while the other account was wearing full steel each time.
I think this is a great way of cheating the system.
