enario:
An Axis soldier with a K43 and an Allied soldier with a M1 Garand encounter each other on the battlefeild. They both see each other, but the Axis aims and fires first. He scores a direct hit to the arm, 90 damage. The allied soldier responds slower aims and fires. He scores a direct hit to the arm, 100 damage and a kill.
This happens all the time, if you think of it this way who has more skill? They both shot the same body part. Both their rifles are semi-automatics, both their rifles utilize a large calibure round. The Axis soldier reacted first, isn't that where-in the skill lays?
As far as all other weapons are concerned, Everything is balanced out well. Except when it comes to rifles, the main-stay of both armies. On the main maps (hill/ava) it seems the allies have the advantage. They spawn with the highground and their primary rifle is superior to the K98.
The K43 was designed to close the gap in this area, its not like the M1 Carbine with its extremly fast firing ability. The K43 cycles its round slower then the M1 Garand. There really isn't a good reason as to why it should only deal an average 90 damage hit.
If the issue of everyone abandoning the K98 for a K43 we can limit the number of people using K43.
