Roaring Thunder mID change

RT currently is a great shadebat dagger and I really want this niche to continue to exist while making RT less powerful overall. Therefore, instead of the current +Lightning Crash mID amplifying Ripple, can I suggest:
+Lightning Crash
Dash becomes a vertical downward lunge. Swan Dive deals 300%N 150% T in one hit, no longer scales off Momentum, and instead gains +20% damage per Mark on the target.

If Swan Dive is not affected by Surprise Strike then remove the part about it being all one hit, I'm not sure if this interaction exists. Alternative Swan Dive part is 5% from Momentum and 15% from Marks. If this is too difficult to implement then just reduce Ripple damage multiplier from 3x to 2x.

This shifts the main damage source from Ripple to Swan Dive and Marks. People will need to pick up the second red node on both shade and acro trees, which means there isn't enough AP to also go for Ult. It requires more of an effort to play the game instead of Ripple Dash jump spam doing far more damage than it deserves. It also makes RT worse for pure acrobat because Swan Dive has both lower base damage and no longer scales off Momentum, and worse for pure shadestepper if you want the mID because Swan Dive requires a heavier AP investment into acro.

Maximum damage per Ripple+Dive with 7 Marks+3 Knives+Ace is from 25x DPS at 5 blocks fall to 30x DPS at 15 blocks, instead of current RT going from ~28x DPS to a little over 40x DPS. For reference, regular acro Ripple+Dive with max Momentum+Ace is 12-14x DPS without Ult and 16-18x DPS with. Regular shade Backstab with 9 Marks+3 Knives is 24x DPS and with Satsu as well is 48x DPS. All calculations assume max Aspects. My source for this section is Desmos graphing calculator.
