Of course no one "intends" to. But I'm guilty of subbing for 3 months, playing for 1.5 and getting bored, and then not fully utilizing my last 1.5 months.
The point is, it's bait to get you on the hook. Once they have your 6 month sub they don't care if you play or not. Hence why the game is dead atm (even before TBCC launched) and no 9.1 in sight.
