I honestly had debated to myself about the ultimate. A teleport like human? No - we don't need those. Got chameleon, Human, and Beast doing that shit already.
What about a suicide bomber? Well.... you aren't really fighting close quarters like a flame predator, nor are you playing like an undead / chameleon. OH OH, BURN PEOPLE. Nahhh, blood mage got that. As well as beast and. . . chameleon...
The hell does chameleon not have? Oh - damaging the killer. Hells Demon has it. Ever been killed by it? I have... many times. I hate them for it, since it hurts. A lot.
Also - Flying would be stupid. We're not making another Santa. Black hole is all Shadow of the Void. Reviving is silly, since the user is gonna die constantly anyways. Complete Invisibility - Flash bangs compensate.
Roots - Athena and Night Elf (and Chameleon!). If this race had it, the roots would have to last approximately 3 seconds, but the CD would be like 15-20 seconds long. Even then, we don't need another one of them running around, granted they would make great compatibilities if you play together properly.
I have also debated on the Eva ultimate, except it spawns a flash bang inside of the target rather than dealing +200 dmg to the target. The reason I didn't do this is well, exactly what people were doing with eva ultimate when eva was out... spam it. I'll pass on this concept.
