Game Design Ninja Charge Feedback

hi this is just a short thread about a small gameplay change I noticed after the Assassin/Ninja vanish buff

Background
As most people know Vanish spell of assassin and the reskined version of it (shadowclone) in Ninja got a buff yesterday. Now there will be a small charge towards the direction the player is looking at. This is an attempt to solve the mobility issue of assassin and ninja class.

By spamming the spell the player can get a short distance charge boost kinda like spamming charge spell in warriors but smaller and more tactical when combining with jumpboost in the vanish spell

Finding
Now the thing I notice is that if you spam shadow clone (ninja version of vanish) although you will get the above mentioned continuous charge effect, you'll leave behind a bunch of "clones" after your each span of the spell. This is nothing big and the previous clone will disappear when you cast the next spell but will probably give away your location and direction if you choose to do this as a quick manuvour during pvp

Solution(?)
When the player is invisible and cast shadow clone again maybe won't spawn another clone?

Disclaimer:
This is just a small feedback so it's open for discussion. Ofc ppl will say ohh then don't spam it but the thing is assassin will be able to do this while ninja can't. Also a nice thing to point out

 

maybe do something like..

every time you cast a shadow clone spell you wont leave a clone behind for about 5 seconds? after the 1st clone is summoned of course

 

ye that would be unfair
