You can add back whatever bug you like it's your game after all.
It was just a big thing back in the COD2 days and as soon as i mentioned this game to people that were really in to COD2 it's always one of the first thing they ask if thats in.
I can even remember a post by @vozER where he said people with a COD2 background where complaining about it on the first LAN you guys showed off battalion.
"what I heard people complaining about was that you couldn't really do reloading jumps (personally, I don't mind, but many CoD2 players did mind)."
in the end of the day it's your choose but i think it would be a great addition to this game. Also it played a big part in why people loved the kar98k so much in CoD2 and it also gives you the feeling you got full control over your character at all times and it highers the skill ceiling thats what you want in a super competitve shooter right?
"that fast paced one to one movement action gameplay"
there was nothing more satisfying than hitting that reload jump shot on the Burgundy cross, the good old days.
And if it's impossible to recreate in unreal engine, or if you guys dont have the knowledge for it it's also completely fine.
I just hope you guys give it a second thought.
