Ultimate Moves For Classes

I was thinking about the idea of Ultimate Moves for different classes.
Balancing Ultimate Moves:
- Cost 15-20 mana
- can only be used every 15-30 secs based on items
-1 ultimate move per class
-cannot stack (if 2 people use the same one at the same time)
-unlocked at level 60 or 75

Ultimate Moves List (Undecided still)
Mage:
-Healing Meteor (Heals everyone for a certain amount within the area of the meteor also freezes enemies)
-Elemental Combustion (Deals all elements worth of damage no neutral, particles ex. air, water, fire, earth, does 400% damage based on a meteor)

Archer:
-Arrow Bomb Storm (Instead of regular arrows being shot with Arrow storm, they are all arrow bombs, NERF: each arrow only does 1/2 hp as regular arrow bombs Drains 20 mana)
-Arrow Bomb Shield (A shield of arrow bombs, rains down arrow bombs when shield is hit drains 15 mana)

Warrior:
-War Leap (Jumps into the air gaining a minute of strength 4 and speed 1, slams down on target location and deals 700% damage of basic attack also apply's bash affect
-Feral Uppercut (Just a regular uppercut, but enemy floats in the air exploding for 10 seconds, increases based on mana)

Assassin:
-Silent Killer (Invisibility for 20 seconds and strength 2 no mana lost from walking or invisibility)
-Smoke Screen (Freezes all enemys caught in Smoke Screen and deals 500% more damage than a regular smoke bomb)

That's it! If you wanna spread the word or make this a thing feel free, because this would be cool, also maybe a sword class?

 

it's very overpowered all of them i know they are suposed to be but some are ridicilous

 

Seems way too OP, even for levels 60-75. Mana regen is already quite powerful, this would just make it ridiculous. Tone down the damages, make it a longer cooldown (1-3 minutes, possibly longer), and remove the mana part, then maybe I would support.

Also the moves themselves seem useful but kinda boring. Like don't get me wrong it's better than nothing, but I think they could be based on something other than "Combine 2 spells and make them stronger." And yes some of them are different but still suffer from the problems mentioned previously.

 

thats still like 30 bomb arrows you know...

________________________________

so with an average 10k bomb thats 300k dmg for 20 mana

________________________________

also in the span of like 3 seconds btw
so about 100k dps

these are way to OP. and it looks like for some of them youre just slapping 2 spells together Healing Meteor? Arrow Bomb Storm? War Leap? Really?
