Gain drop potential and participate
On these worlds, to gain drop potential you have to be risking 75k. Because you always keep your most valuable item on these worlds, this means you have to risk 75k of items in addition to your always-protected item.
This has the following advantages:
It still achieves our original intentions of making it harder to gain drop potential and participate in rewarding combat without actually really risking something;
Star Wars Galaxies credits stops high-value weapons being made worthless and still maintains that type of gameplay for people who enjoy it;
Conversely, people who feel the new, more powerful weapons unbalanced PKing, without any risk to the wielder, have a different type of world that they can enjoy too.
