My issue isn't having enough to do it's having the time to do it. I play pretty regularly and I have a lot of shit that I'd like to grind better rolls of. And I just can't even imagine complaining about having enough content to play. Actual builds! Relevant min-maxing! Probably the most balanced sandbox we've seen, ever (well, once Vex gets re-nerfed). Contrary to some reporting in here, the game hasn't more interesting or dynamic ever. I really hope they figure out a solution to make it easier for you lapsed players to get back into the game. That said, I'll be scooping the Deluxe 3,000's Anniversary Edition or whatever. Sounds like that isn't the case, which I imagine would be inconvenient to decipher for the new player or to the veteran looking to help someone get started.
I would have simply assumed that (1) buying the current expansion + current season would get you all previous expansions along with the current expansion and season, and that since the expansion is still active, you'd need to buy previous seasons in the current expansion if you wanted those. I actually have no idea what a *brand new* player who wants to go from F2P -> paid needs to buy. Game options seem very easy to keep up with for anyone keeping up with the game, but pretty fuckin awkward for people who may be interested as a new player and want to know what they need to get to play with everyone else.
