On one hand, when I see people use the OSCAR, they tend to dominate with it and absolutely shred anyone in their way, long range and short range.
On the other hand when I use the OSCAR, I can barely hit anyone at range even though the Joker Carbine and OBIR can both manage long range poking just fine, and when I try to CQC with the weapon my need to adhere to proper fire rhythms means that people with full auto weapons can just hold the button down and delete me.
So, what gives? How do I use this thing right? What mods does everyone run for it?
