I like the concept, seems real fun! This is definitely a late game hero, those level 13-20 talents are all really strong. Mixed with the stacking on his trait this guy could develop into a real monster. A question: Chitinous Plating (E) has a mana cost and a cooldown but says it is a passive. How does it work exactly? A few ideas: Regeneration Monster(Level 1): A change to make the quest reward more in line with his trait. Rather than a simple bonus 20 health regeneration, maybe something...

What's the range you were thinking of for Penance? If its too short it could be disastrous, being rooted is never good, especially not for a squishy healer. The las thing any team wants is their support getting themselves killed.

The reload seems really long. He doesn't have the unlimited mobility or blistering attack speed, nor a particularly strong basic attack, to warrant such a long reload.

If you wanted a bruiser then I like this. It would be hard to have him as a true tank, though. The crowd control reduction is a huge benefit but he lacks sustain or peeling ability.agf

I like the way you handled resurrection. This is a nice design.

I like the concept but it almost feels lacking to have an arcane mage without arcane explosion. spamming that skill was my favorite reason to play arcane in WoW.

On that note I would recommend a buff to Doomgaurd. It may be able to target a particular enemy but it has less health and less than 1/5 of the damage of Gargantuan. Since it can be targeted you don't want to go overboard but 10-20% more health and double it's damage still leaves it significantly weaker than Gargantuan. and maybe for a level 20 buff instead of duration and health/damage maybe you can summon two. one that you target and one that stays close to you targeting the closest enemy,...

The larger problem with the 5 was the scaling. At level 20 the attack would only be 11. That's 55 damage per clip at level 20. At base 15 it is at least 153 damage per clip at level 20 which is still less than multiple heroes' level 1 attack damage. But not quite as laughable now.

Only comment on this is her basic attack, it is so low that she would probably be better off never attacking. 7 is just a bit low, definitely needs to be raised.

I like the concept a lot over all. Your trait is actually really creative and seems to be useful without being too strong. With that being said I have a few suggestions for the abilities that could make them behave better. Also, your talents are a little generic, I have some ideas there as well. Mark of the Naaru (D): Change base healing to 60 (+4% per level) health over 5 seconds. Every 4 stacks of Resolve increases the amount healed by 15% and lowers the amount of time its healed over...
