Please do not swing to the other extreme. As it is, it already sound like MP trade plans will be DOA.
People talk about MP gameplay abuses in POE, but those are exploited only by the minority (multiboxers, extreme coordinated parties, etc), with the broad base of players heavily incentivised to avoid public parties as most POE progression dont facilitate MP play. I would be very disappointed if LE effectively become a single player ARPG with online/MP only in name.
