These are the two aspects that bother me about BFV.
I have ALWAYS been partial to the support class, as I was a Machine Gunner IRL. I LOVED how in BF3, the suppression mechanic meant you did NOT go head to head with a machine gun and expect to win. Not only were the weapons dangerous (which they are in BFV) but you could also force a group of players heads down, allowing your team to move up.
In this game, cant really do that. Sure, you can gun a person down easy enough (except good recon player, I will get to that in a sec), but if there is more than one person, RIP.
Keep in mind, I play more "realistically", using machine guns in longer ranged engagements, and avoiding run-and-gunning. Im MOSTLY concerned with the MMG's, LMG's it would be nice to have, but I get they are the more mobile run and gun weapons for this class.
My biggest issue with no suppression, comes in when dealing with a good sniper.
If the sniper is good, no matter how good you are on the Machine Gun, if he sees you, you will lose, even if you get first rounds on him.
The result then is that, with the current meta with a LOT of recon players, playing a Machine Gun class in true style is borderline suicide.
NOW, I get that adding suppression to Machine Guns would hurt Recon in long range engagements (arguably their ONLY effective range)
That's why, id like to see Recon be allowed 1 hit kills (not on limbs) in close range.
The reason is 2-fold
1- Giving them an extra something now that Recon is not the sole king of long range engagements
2- As a player who enjoys authenticity, I often use Recon Iron sights (MOST British troops were armed merely with a Basic Lee-Enfield) and while, sure, these weapons ARE at a disadvantage even by realistic standards, its still annoying that I can BEAM someone right in the chest with a .303 and they just ignore it and still kill me. Basically, this means it is borderline IMPOSSIBLE to use bolt action rifles for ANYTHING other than max range. If you don't have a scope, well, tough luck (mid range isn't bad though)
Ive been hoping for a Hardcore mode, but since apparently BF1 didn't have it (never played it) im guessing we wont here either.
(P.S.- Honestly, id be fine removing the scope glare effect from snipers if they feel that 1-tapping in CQC isn't enough)
(P.P.S.- The ONLY balance concern would be quick scoping, I can see that being broken. As long as that isn't allowed, we should be dandy)
