I do find funny that top streamers get upset at changes. They are the minority of the playerbase and can't expect the game to always appeal to their specific needs and tastes. If they are good at the game, this shouldn't break it.
In Battlefield V, for example, the original game was very attrition based. Low count of ammo, a balanced TTK, everything making a very tense combat system. The "ambassadors", streamers and top players, got frustrated that they always ran out of ammo and couldn't keep their kill streaks which wasn't fun for them. After the beta, DICE changed it. The game began losing their vision, and, well, then started a series of good and bad decisions trying to please everyone. Streamers and top players are an important part of the playerbase for different reasons, but you can't always do things in their favor. If a change actually levels the player field, then it's a good change.
I mean plenty of lower level players also complain about shit, they just have way less perspective on the overall game, and it's not as broadcasted, unless your looking at reddit.
Also they are good at the game, there's really no debate there, the game has just become less fun overall for them, and suddenly not being able to do fun things is a feels bad.
I'm curious on how this will actually level the playing field? Due to sbmm, or whatever version of this they have pub matches should usually be more competitive and people not great at the game won't encounter them, and even without tap strafing they would have never stood a chance. These players are also high ranked so unless they are smurfing it's no big issue there either.
If your idea of leveling the playing field is putting easy to use op weapons in the game (such as pre care pack spitfire) or broken characters ala seer, then I am in total disagreement.
Tap strafing may have been unintentional, but I fail to see why that must be viewed as a negative. The game is evolving overtime, due to the players, and there's a beauty in that.
This is something the devs decided for themselves, there was no major outcry for the removal of tap strafe, low level players weren't cowering in fear of people Matrix dashing at them, they are too busy looting for 10 minutes and dying to ring. That's not a slight, just an example of the difference we are talking here.
Apex has always been the movement BR, above everything else I have ever heard anyone talk about or what I've seen other people say when I seek out others opinions, it's always the movement that has made it stand out. So I can't say I see anything that goes against the team's vision, muddy and vague as that vision is.
