I actually never said it was clearly printed, only that it was somewhere on there. It's becoming obvious it they should find a better way to get their requirements across, but I guess it's more along the lines of how all companies are boxing their games. I haven't gotten a store bought game in a while, but retailers should really be asking customers if they meet the requirements, but I guess most just assume they know what customers getting into.
A server connection is required as this is an online-only game, there is no offline or singleplayer play (unless it's a private garden ops match, but you're still required to connect to the server).The game is pulling character levels, character unlocks, all your progression and inventory from the server, as well as linking you to other players for matchmaking.
