I do believe as well that all long time players understand roughly what the kyro grind feel like.
Back before Kyro all toon progress was gated by a combination of carbs, stun guns, stun cuffs and to some extent golden eyeballs as well.
The introduction of Kyro have lead to the removal (more or less) of that particular bottleneck.
Considering for how long those other pieces were bottlenecks I think it’s premature to expect any change and a new gear piece to replace Kyro as a bottleneck.
I wouldn’t expect CG to change Kyro to any meaningful extent as a bottleneck in the near future, when they do it’s probably going to be in response to sub-relic to become completely meaningless in power level.
