Do you have WanderingMystic blocked? I find it really weird you are considering my (As you admit) accurate statement to be myopic and near-sighted when the post I was responding to stated "Dual welding only used to fall off if you are a fighter of 11th level or higher. Now with the cleave property I think that those will definitely outpace your dual welder."
I was showing that, yes, it does fall off, but not by much if you don't account for the feats. And if you account for the feats, a Dual-Wielder can have OTHER feats that may be good for them. I even gave an example of a pretty good set-up.
Yes, as people keep saying and as you admit, Dual-Wielding does less damage at higher levels, but it isn't because Dual-Wielding is an inherently weaker fighting style or anything, it is because there are not as many damage boosting feats. IF you have other things you want other than damage then this isn't an issue, and I felt that was obvious. I mean, both dual-wielding and Great Weapons do more damage than Sword 'n Board style for all the same reasons plus the lack of a bonus action attack. But Sword n' Board inherently has better AC, because that is the obvious trade-off.
The thing is, Dual-Wielding also trades that AC for more damage, just delivered a different way, and if you were following the playtest feats, Dual-Wielder feat might no longer give an AC bonus which will mean it gives that up to the same degree. Yes, obviously you can take the skilled feat or tough feat or inspiring leader feat or a dozen other feats. But by correctly identifying that the problem is located in the feat support, if someone WANTS to increase the damage of dual-wielding characters, then they know not to focus on making them as good as a PAM+GWM+Charger Fighter with no additional feats, but that they should instead be looking to homebrew feats that allow for Dual-Wielding characters to do more damage.
And if you don't care about increasing Dual-Wielding character's damage... then there is no issue to begin with.
