People have always complained about Deku V2 having an underpowered ult. I think it comes down to 2 things: 45% and whiplash are both terrible moves.
45% is easy to dodge, and is not combo extendable, making it basically useless.
Whiplash has trash damage and in order to combo extend, 120% overdrive has to be used. It also has a tiny range and terrible endlag.
Here is how I would fix it:
If you ever saw Legends Battlegrounds Jun moveset, the 4th move can extend off the 1st one with a variant just by pressing the button after hitting the 4th move.
We can do the same thing here, as after you hit 45%, you can then press whiplash and the game will automatically use a new variant of whiplash to allow you to combo extend. This would fix both moves, as 45% can now be combo extended and whiplash can be used in general. Perhaps the whiplash variant will have lower damage (10-15%) so its not too op.
What do you think?
