About barge:
People say that jumper kill activity (even if i dont like to jump myself).
I disagree, when people jump, they are at least 3, most of time 4-5. This people can RP well (even if some jumper group dont) and it would be bad to punish everyone when only a minority use this to powertrade.
About PoB:
I think that PoB itself isnt really the problem, the problem is that their arent enough variety between PoB. As you can see in my thread, we propose different way for PoB. Like this, someone who build a PoB with a lot of WP to block a minefield wont be able to Stock a lot of Ore in it and it will mostly cost him money.
If he decide to build a "Trade" PoB, he will be able to stock a lot of Ore but wont have a lot of WP (only 1-2) and wont be able to block the field. That's just a proposal, i let you give your mind
