And again, aside from the anti 5C the rest of what Sandro suggested relied on Open to really work as suggested.If the OP of the Flash Topic thread had not had Open only as one of the proposals then it would very likely have been introduced by many of the participants in that thread.
That notwithstanding, the ensuing focus on one particular part of the suite of proposals, whether in support or opposition, swamped the feedback on the rest of the proposals - proposals which seemed to be well received and not at all controversial (and could have benefited all participants in the feature had they been implemented a bit over three years ago).
Without open uncapped UM would make for even more grind in solo, unified fort direction would be pointless, just as lowering the BGS footprint would be pointless. These synergistically work with open to bring people together by condensing down the areas Powerplay works in, and (in uncapped UM) makes it a magnet for players.
