Assassin/Ninja class

Currently there are 3 classes in the game and since some servers have up to 20 people (10 people each team)
i think it wouldn't hurt to add a new class, and I've been thinking of something balanced that would receive an even amount of attention from everyone that also like the other classes, is always good when the player is. so yeah, its a ninja, here i made a list of everything I thought of about him while coming up with a class.

Appearance: a slim looking character with a dark team colored robe and two daggers

Controls: LMB: A simple jab using both daggers witch can be done about every second dealing 1 heart (1 half when attacking a knight with his shield out(ninja agility taking place))
Holding LMB: charges an attack for about 2-3 seconds, you then can release to boost wherever you mouse is pointing dashing in the air or strait through multiple enemies dealing an additional 1 heart to each.

Items: Shurikens, dark pearls (or whatever you wanna call them), flashbangs, and maybe some torch you can throw to start fires although that may make the archer less unique.

Item Usage: Space bar: Consumes a dark pearl, creates some smoke around you player and teleports you to wherever you were pointing your mouse (and obviously can't teleport more than about 20 blocks from your player) Kinda like the weak wizard in the fun mod. oh yeah, also there's a cool down, duh.

RMB: you either fire a shuriken or a flashbang depending on what you selected in you inventory
flashbang: when thrown creates a 10 block or so radius of light and any enemy caught in it will be stunned for about 5 seconds kind of like a water grenade

Shuriken: can be thrown every, like .7 seconds dealing half a heart of damage and block-able by shields (something to damage your enemy before finishing them off.)

Abilities: Has 2 hearts of heath
can run jump and climb slightly better than any other classes

my item price thoughts:
shurikens: 8 for 25 gold
shadow pearl: 1 for 35 gold (also possibly spawn with one)
flashbang: 2 for 60 gold

strategies:

throwing flashbangs in a big war
teleporting behind an archer up in a tower and killing them
using items to your advantage in 1v1s
teleporting into halls and out of flag posts.

so that's about it! thank you for your time! also please don't judge me negatively just because i dont have an avatar. once again thank you for your time
