Sage's only cast speed buff comes from the second attack in Kibelus Training which is their basic attack. The problem with it is that at 5% its not really that strong and most of the time during combat unless you prioritize getting the second animation of that attack you almost never have it up. I think it should be moved to a common skill like Shock Relay their RMB while also getting buffed to 10%, this would make it more reliable and also help with how sluggish Pre-Awakening can be. Sage has a handful of ways he can switch from Awakening to Pre-Awakening but the speed disparity between the two can make combos that need to switch weapons less than ideal.

It seems like a really cruel joke that they put his speed buff on THE SECOND HIT of a really slow attack string.

I'd really like them to improve Overcharged mechanics so that it allows pre-awakening and some Awakening skills to cast 25% faster.

Also the utility of Black Spirit: Flow: Interrogate's attack speed buff is kinda gimped by the fact you can't cancel out of the animation right after attacking. Only the normal Flow: Interrogate lets you Bolt out of it.
