Reduce Infernal Rain damage by 25% after lvl1

[horselance]

*push*

Did one ever calculated the rains overall damage?

At lvl one: five waves per 640 damage, that 3200 damage for a level 1 skill on EVERY target within an area of 900 in every direction around the infernal while moving around.
Sky Fortess does with lvl1 bombs 5x500 damage within an area of 150 and damagin itself?
Titans hailfire and devil explosion do 1000 damage each...

I think even the initial damage is too huge besides area of effect AND moving ability.

You compare 18k tank's ultimate vs 16k tank's normal skill? And also all ultimates start with 50% power and goes up to 100% power at level 5.
At level 5 SF deals 12500 damage and Infernal deals only 6400 damage. No need to say a normal ability can be lvl 5 at tank lvl 13, where ultimates at lvl 22.
Even Demolisher's ultimate deals 2250 damage in an 150 AoE.. Though its a DoT spell but needs no channeling. Inf Ulti can be stopped with a stun.
