Consistency is nice but the itemisation for the buckles probably needs a bit of a rework. These buckles give very little in the way of stats and the stats they do give aren't particularly good. For comparison let's compare the tank buckle to the stuff a Guardian is able to equip in its additional slots:
Where Brawler gets ~72k phys mits and ~2.2k max power (power not being a stat people want to see on gear) a Guardian gets ~205k phys mits, ~92k Crit defence, ~19k vitality, ~145k Block, ~11k Might, ~6.6k Fate, and ~117k tact mits. Bear in mind that LI Heraldries give the same amount of stats regardless of whether the LI is 1h or 2h, so there's a pretty large stat difference between Brawlers and Guards.
I will admit, Guardian gets a bit more in the way of stats than most classes but Brawler still lags behind stuff like Bear who gets offhand + bow, or Champ (who can choose to offhand+bow or just stick with 2h+bow, either way bows have notably better stats than these buckles).
On the DPS side we have something like the following:
A smaller difference but still a pretty notable one, Brawler is really lagging behind in stats. Feels like you've given Brawlers similar stat totals on their belts as LM stickpins when LM is a class that also gets to benefit from an offhand weapons stats, as a 2h only class Brawlers can't do that.
Weather Blows being useable on the move is a pretty solid QoL improvement, definitely feels better now.
The Come at Me change is solid, brings the class much closer to parity with other tanks in terms of range, the target improvement is also welcome. Another good improvement here would be having the yellow line AoE target trait apply to the taunt, I'm not really sure why it doesn't and I'm not fond of the AoE target count tracery being pretty much required for Blue here.
I'd also like to suggest considering changing Come at Me from a Point Blank Area of Effect ability to instead function as a targeted ability. Brawler currently is very melee focused with its ability to aggro things, yes it has Hurl Object to tag a ranged target or two but for the most part you have to run around a lot to tag mobs which isn't too great on a class without a runspeed buff. Classes like Guard/Warden get around this a little bit by having melee abilities with large range (and solid aggro mods) such as Brink of Victory or War Chant but I don't think such range would fit the flavour of the damaging Brawler melee skills. Making Come at Me function as a ranged AoE taunt might help get around this a little bit.
This is definitely the change I was most interested to see and honestly it makes a massive difference, the class feels much snappier now. A slight side effect of this change is that it's a lot easier to maintain stacks of Innate Strength since you can easily generate enough Mettle to use most spenders off cooldown (and thus don't really need to think about maintaining the stacks).
I'm still not fond of the quick/heavy/balanced breakdown of skills, definitely still of the opinion that tying the buffs to Setups is the way to go here as it would require a little bit more thought to ensure you maintain all 3 Innate Strength buffs. I also still kinda believe that Setups should do a bit more damage by themselves, they make up a lot of the key presses on the class and right now their damage is really negligible.
Overall this is a positive step forward for Brawler, it's by no means "fixed" or even a particularly good choice yet but it definitely feels nicer to play.
