New Conqueror. What should be done to balance it.
First of all there are gonna be champs that are gonna able to able to abuse it and those champs are gonna be broken. Second, the heal needs to go, it's not Grasp, it's Conqueror, its a tank killer keystone rune. So here is what needs to be done.
-
Remove the heal: it's too much on such a rune.
-
Make true damage melee only, bruiser have a hard time killing tanks so let them have it once it's reaches 5 stacks, otherwise it's fine.
-
Reduce the bonus AD for ranged champs by half but keep duration the same for both types of champions.
-
3-10 extra AD for 10% less true damage is fine.
-
That some champions abilities or kit stack Conqueror faster, some champs should be able to stack it quickly if their abilities allow it, otherwise it becomes unviable on those that need it.
Otherwise they did a good job with conqueror.
