Meet the Remington R4.
You may know also know it as "that gun that literally 80% of Riflemen use in 1-10 servers and that 100% of low rank Rifleman use in normal servers, which performs on par with a capsule gun".
But it's not a capsule gun. It's a euro shop gun. One that you can get at an extremely low rank.
Did I mention that its been this way since the release of the gun?
GREAT idea. Lets have a low rank assault rifle which is massively superior to every other assault rifle available at low ranks, and performs on par to guns that are much more expensive and difficult to get!
It's a decent gun, but it's not more OP than the m4mk3 used to be, it's not especially great at long, short or mid range it's just decent in all ranges which makes it a really versatile and easy to use gun = perfect for beginners. According to you, players with more experience should be able to destroy beginners (who would be using super crappy weapons) with all the good guns in the weapon shop. I don't think that's fair at all, actually it's pretty selfish.
+ I can outgun the R4 no problem with para, f2000, Sako, SG556, xm8, mk3 etc so....
