The rt ladder died because
1. Long waiting times between games. It only checked parings every 5 min.
2. Random templates. Most players disliked 1 or more template
3. Few players over time as interest slowed in the ladder decreed. The ladder was also 'level' gated and hard to find for new players.
I think QM, addressed all of 1,2,3. I don't want the RTL back, or at least not in the way it was. I would be much more interested in something like a seasonal RTL, where ratings and template was changed. (In fact, why not make it the seasonal template?) It would also be key to have something like the QM parings, so you don't have to wait.
With that being said, there is a working RTL from -B, and I would rather Fizzer spend his time on other things.
