I think a "rough timer" is a good thing you just need more emphasis on it being an estimate. It's going to be near impossible to pin down an official release date for the each season but that's why the double exp until release is a good incentive.
If the community misunderstood the countdown and thought Season 3 would start at the end of the countdown it's because it needed more explanation.
You can understand why players would believe that the end of season would naturally mean the start of a next.
Plus if the timer ran out and players were suddenly recieving no experience points, no levels and no loot that will turn players away from the game because they are essentially playing for nothing.
Maybe instead of a countdown in days to could just have something along the lines of "Season 3 Coming Mid December" so it's more vague but playes get the sense of urgency to unlock their loot before the time comes.
When I said there was misunderstanding, I meant it was because of the poor design, not that it was the communities fault.
I try really hard not to blame things on the design or Devs, they're trying their best, and this is just a case where a feature wasn't really done in the best way.
When players unanimously don't interpret something in the way it was intended, the feature is flawed and not communicating what it's supposed to. The fix for that is changing the feature, or removing it. We're leaning towards changing it now - and making it more obvious what it actually means.
