That was intentional, really. With the massively rising costs at higher level I feel the ratio would have to go up considerably to make the forging feel significant, more so since the other source of free timers (actual time passing) becomes less and less relevant compared to what towers need.
With what I proposed you’d get:
Level 100 (lvl 31 towers, 12 hr timers forged in 30 hours):
- Forging timers for 1 tower takes 48 days
- Forging timers for 1 level worth of towers takes 51 days
Level 200 (lvl 48 towers, 24 hr timers forged in 24 hours)
- Forging timers for 1 tower takes 42 days
- Forging timers for 1 level worth of towers takes 50 days
Level 300 (lvl 61+ towers, 48 hr timers forged in 18 hours)
- Forging timers for 1 tower takes 29 days
- Forging timers for 1 level worth of towers takes 109 days
While the amount of forging needed for a single tower drops, the amount needed for a single level still goes up. I hadn’t done this math before suggesting the numbers by feel, but I think to keep timers relevant they do need to sync up with the cost of a level more than the cost of a tower.
Of course a fix to the 300 wall might potentially shift this, but as the leveling curve stands, I think these large jumps make sense, as does synchronizing access to the cheaper step to the places where the xp per level leaps up.
