Plasma Blast need some love (again)

Got three question here :

1: Why can't we reduce the two added second ?
Take Bone spear for example, Channeling too, can be launched before maximum charge , doesn't take 3year and a half to be charged to max too, and doesn't need a WALL (but it's my third question soo I'll get to it later) and you can reduce the cast time !


2: Why are the three shot with scatter so FREAKING slow ?
On every other skill I tested it with, the projectiles shoot almost simultaneously BUT with Plasma Blast it's like "shoot - pause - shoot - pause - shoot" and a lot of time and I mean a LOT , you'll have to dodge roll out of some shit and just never shoot the second and third laser after pulling a boss.

3: Why does that spell only does damage on tuesday ?
Sorry I mean on wallhugging boss or monster ? the explosion is a fun idea but when most of the BIG boss have big arena and or no wall , what's the point ? I'm only noticing it on bosses like Vaal Overseer 2.0 and the giant kobold thingy in the crypt , otherwise , yeah it's here, it exist .

Add to this the cluckiness of the crossbow and you get and underwhelming skill.

Thanks for reading me . (Maybe ?)
