Although linear, all of the paths are actually extremely wide and open except in the immediate middle, allowing for plenty (local) flanking options. Because the map is relatively flat and continuous, Dynamos are really mobile and fast through unturfed ground or enemy ink by effective flick dashing. Virtue to the fact that there are a lot of entrances between the 2 functional sides of the map, there are a lot of ambush options to take out inattentive chargers. Taking/forcing people out on the wall is trivial as a Dynamo as well once you're close enough (and it's extremely difficult killing people if you're on top of the wall yourself and they're immediately below you hugging the wall). Also thanks to the long range, you are very well capable of reaching the other half of the map fairly easily even from atop of the wall of your own side, while other rollers are relatively strictly confined except for bombs and sprinklers. Additionally, there are a lot of un-inkable walls you can take cover behind and hide from chargers while the Dynamo is able to flick above and over those walls, taking whatever is behind them (splat zone or a hiding enemy). Lastly, what the Dynamo can't accomplished can be done with a well-rolled Splat Bomb.
I still kinda suck on the map currently because it's new and fairly intricate, but so far Dynamo feels really comfortable on it. Haven't faced a (good) charger on it yet though, neither in TW nor ranked. But I'm fairly optimistic honestly
