I think I figured out how to solve the tank issue.
Give flat magic pen and lethality items more lethality BUT the catch is that it scales and you actually have to land abilities.
: 45 movement speed
4 magic pen
New- Unique:Growing power: Landing an ability stacks magic pen of 6 for a total of 22 magic pen(that includes the 4 magic pen.
: magic pen reduced to 10 from 15
New-Unique:Corrode: After landing 3 abilities, deal 10-40 bonus magic damage
Duskblade: 3-8 lethality depending on level
New- Unique: Piercing blade: landing abilities grants 4 lethality for a total of 12 lethality
Changed-Nightstalker: Same as before and proccing nightstalker applies all stacks of piercing blade
I'll update the list When I can think of more stuff.
or
Just run up to you, press R, miss some of their abilities, then auto attack and kill you. The idea is that you're REWARDED for playing good, and PUNISHED for playing bad.
