No it doesnt. The kill radius of infantry for the ml-20 was almost halved. It was like 5.4 meters, now its 3.1 meters.
In comparison , the kill radius of the LEfh is 4 meters.
So even with 200 damage, ml-20 will still be less lethal againts infantry because of less fired sheels, less AOE, and slower rate of fire.
The ML-20 was one of the cases where Relic messed up.
ML 20 152 Artillery
We want to encourage the use of the ML20 which was previously underperforming.
Salvos increased from 4 to 8
Removed precision strike at veterancy 1
Veterancy 1 now increases the number of salvos of the ML 20 by 2 (10 Total)
It wasn't underperforming. It was rarely built because Relic made the poor decision to give a badly OP Close Air Support commander to everyone, which made on-field arty useless. I'd take the old one back in a second.
Reducing the explosion radius was a really poor decision. It used to be great blob control when you could build it. Now it isn't. With this group of strange buffs and nerfs, the Soviets have a unit that costs 600mp and doesn't do anything well. Buffing the damage back to 200 won't do much for it as long as the blast radius is so small.
