I will continue editing this post as after we discuss things we come to different decisions on how and what needs balancing. I'll start off adding some things I think that need balancing, and through discussion I will add more and edit the ones posted.

Spells:

Cold strike damage should be very close to death coil damage.
War stomp damage should be reduced.
The attack/move speed aura should be increased.

Tech:
Undead tech needs a considerable hp boost, especially the first 3 tiers
I think that a hp upgrade should be made available to all tiers from tier 0 onward.

Items:
I believe it's time to remove the stock delays on many items, especially the more basic items like precept of mana for instance. It's not going to change game play hardly at all and will allow the newer players a better chance of building the item they want. Pro players are more likely to stand beside the shop as it becomes available, preventing the newer players from being able to buy them also.

Thats all I will add for now, I will edit and add things as we discuss. Please do not flame my opinions or the opinions of others in this thread as that is not helpful, thank you.
