What you say is all true. But that doesn't mean the game is less skillful.
If anything, sniper rifles SUCKED! And yeah, now the triple take is great, and it should be used by you for sure. All seasons have gun meta and energy guns are clearly meta this season (except the L star, go figure, but LMGs to me aren't that useful now unless you are running Rampart).
Skill is not, obviously, just hitting your target in the head with a bullet. It is positioning, fighting the fights to win, using strategy as the circle closes, blah blah blah you know. And frankly, with sniper rifles being okay (Charge, TTake, Longbow if you have skullpiercer...) thats definitely a more positioning, more field of view gun. What you need to do, I believe, is contend with snipers which you really never had to do before. And that means really being aware of how visible you are even if you don't see bad guys.
I say these things and sometimes people are like 'I know what you're talking about! I do that!' I'm not saying you don't. But I'm saying everyone needs to do way more of it. Personally, I like the meta, with the exception being at close range energy weapons are so good you don't even use shotguns anymore. The Volt is a little OP but the 301 both has longer range and is switchable from single fire to burst. Probably, sure a volt can outgun it at short range, but it can't compete at the mid to end of r301s spectrum. Which...is the way its supposed to be. Me, I still like the 301. But now, I'd rather carry a hemlock...availability willing, of course. And I still go for a 301 every now and then. (Hemlock needed a buff and got it)
So...I don't know, I'm just trying to help. I think the meta has shifted, and it is for the better. But it sure isn't the way it used to be. I think proper adjusting is only good, and again...only the shotguns now need a buff.
And Sentinal, because you still suck Sentinal!
