That's the entire point of the stack mechanic: to lower his strength in lane and attrition but to keep it high during teamfights.

If kassa had E on cooldown only, he'd be able to burst the enemy champ repeatedly every 8 seconds with a burst similar to that of another AP carry using his ult. With the charges, the enemy champ can decide to refrain from using spells to push/farm/retaliate and have more time to farm before he gets burst again.

It's part of the strenght-weakness-way to overcome the weakness mechanic. Strength: Kassa can burst you every 9 seconds really hard. Weakness: The enemy can choose not to charge your force pulse so you can't burst as hard. Way to overcome the weakness: It doesn't matter because you have sustained DPS in W either forcing the enemy to cast spells or get damaged.
