Need help with ability balancing

[Drain Pipe]

Ok so i've made a hero and i've gievn him aal of his skills, but his skills don't seem very balanced int hat there are three active spells and 1 actiavtable spell. He's pretty much pure damage and i don't know what i should change.


Now heres a quick list of the skills


Roll-out: I've already talked about this skill, my hero is a pandaren, and he rolls up and rolls in a line, rolling over units stunning, dealing damage.


Thats a keeper

Next one is

Arctic Wind: He breathes out a cone of frost that slows units and deals small damage from cold every second for a fairly long time. I also rigged this one to freeze units if their health dropped too low (since it practically deals peanuts, i set the freeze rate to 10-15-2025% of their health before it freezes them for a relatively long duration. the small damage is to take care of weak units and basically cripple heroes, but not be very powerful.




Thones i think need to be replaced


Giga freeze (crappy name, didn't fell that origional that day)

Basically a war stomp with a ginat glacier animation instead. It freezes units and deals high damage. It's instant AOE and i figure it's unecessary so if anyone could give me some suggestions to replace this one i'd appreciate it.




Last but not least his ultimate, the actiavtable.


Iceferno: Activatable immolation that basically burns units like hell. He also gains a phoenix type ability that fires frost bolts out at units. Anyways this was used to complament the freezing ability and go with the rest more as a boosting ability than a super ultimate.


Perhaps replace this with something completely different



If anyone could make some suggestions for both spells. A passive would be nice but im trying to get all of his skills to stack because he deals relatively low damage with his two actives, so perhaps a cool active ultimate and a nice passive would be nice.


Please be as creative as possible, and remember, he's a pandaren and i'm using a modded fire pandaren moddle so keep the anims in mind.


Hope to hear some good ones.

Balancing stays in numbers. This means that you can increase the Mana Cost for powerful spells and lower it for weak ones. Also, Damage, Healing Bonus, Freezing Duration, Range and all other stuff are also very useful in balancing a spell.

ok well ok but what i truely mean is that most heroes skills are balanced as in they suit the hero and they all aren't one type or another. I'm looking for spell suggestions to replace my panda's ultimate and second skill.
