Basic Attack looks so basic

I am a huge auto attack enjoyer (welp)

I think it is a nice addition the the game, that an basic attack is actually viable. As it is currently my main skill throughout the campaign with my ranger I have some feedback.

1. Its looks very basic (obviously)
I am running an elemental bow (cold) and doing a lot of chill and freeze with it. Why cant I have arrows shooting that somewhat resemble the main element of my attacks? This is also the case for rain of arrows, it looks not as cool as all the fancy lightning skills.

2. Sockets
Currently, it seems like support sockets for the basic attack are unlocked by level. While this is nice and cheaper, I would prefer being able to just slam jeweller orbs onto the basic attack to allow upgrading it whenever I find one. This it is basicly a skill why holding it back behind some level cap?
