Sounds good, but the sudden drop or lift needs to be a risk of somekind.
It would be cool to add a new tool to conflict both hydro and chute.
A tool alot like the pheonix claw, just for vertical meneuverability.
Problem is, what does this tool do to make both going up and down faster consistent?
Still though, the tools need to be a bit punishing of use because it can be such a game changer. However, if it were to change like this, we would see alot more vertical meneuvers i feel if i think about it. Its just a question of if it is needed or not. Currently, the effects are satisfactory, maybe a bit of a buff is required for chute vent. Maybe simply let chute vent work like how you mentioned but keep hydro the same. I donnu, its a very narrow line of thinking that changes up alot if done.
Dont know if i make sense.
But i do believe the 3 second commitment is there for a reason.
