If i'm not mistaken one of the main reasons it took so long to down twintania was gear restrictions? Having to repeat t1-4 while saving up only 300 myths at a time is a pain staking long process. Esp for the groups who only see the same gear for 3 weeks in a row. With the introduction of turn 6-10 it will be much easier because, thanks to CT more people should have progressed through a least turn 4 but should finish T5. As we wont be missing the bridge gear i80 anymore. Since you will need mostly i90/i80 gear to down tear 5. We already have the i90 gear from myths/coil, so no one should really be under geared when entering T6 -T10, unlike T1-5
