Sean K Reynolds recommends I post this in the main brawler discussion thread. Please be gentle, but consider the ideas:
I am a big proponent of class diversity and flexibility; that is why I strongly support class designs that make use of abilities such as rogue talents, rage powers, arcane exploits, and so forth. I really think that the brawler would benefit from this as well, and along those lines consider the changes to the class suggested below.
Weapon and Armor Proficiency: A brawler is proficient with all simple weapons as well as all weapons in the close weapons group. She is proficient with light armor, but not with shields.
Martial Maneuvers (Ex): At 1st level, a brawler can spend a swift action to gain the benefit of a feat she doesn't possess for 1 minute. The feat must be a combat feat or a non-combat feat that the brawler could acquire through her brawler skills class ability. The brawler must otherwise meet all the feat’s prerequisites. She may use this ability a number of times per day equal to her brawler level. If this ability is triggered before the duration expires, the brawler loses the previous combat feat and gains a new one in its place. If a feat has a daily use limitation (such as Stunning Fist), any uses of that feat while using this ability count toward that feat’s daily limit.
At 6th level, a brawler can use this ability to gain the benefit of two feats at the same time. She may select one feat as a swift action or two feats as a move action. At 10th level, a brawler can use this ability to gain the benefit of three combat feats at the same time. She may select one feat as a swift action, two feats as a move action, or three feats as a standard action. At 12th level, a brawler can use this ability to gain the benefit of one feat as an immediate action.
When acquiring feats after the first using this ability, the brawler may add and remove a number...
I have to say Lorekeeper, these are some good changes, though I do have some concerns.
The big ones are the skills related to the Martial Maneuver ability, like Extra Maneuvers, Enduring Maneuver and Extra Maneuver feat. The reason is because these almost seem like mandatory. The 1 hour duration from selecting Enduring Maneuvers twice isn't so much necessary, especially if one were to take Extra Maneuvers. By 10th level, you have 20 uses of the ability, each lasting 10 minutes, just for taking Extra Maneuvers and Enduring Maneuvers (once). If you took it a second time, that's 20 hours of bonus feats.
Extra Maneuver feat: is it 2 feats as a swift, 3 as a move, and 4 as a standard?
The other big thing is I notice you removed the bonus feats. This is kind of an issue, as, without the bonus feats, the class has a hard time meeting all the feat per-requisites for Martial Maneuvers. This kind of forces the class to only select between a handful of feats that it qualifies for, instead of being able to play a martial tool-box.
I'm not sure I like that the Brawler can get up to a +6/+7 Dodge bonus using Brawling Dodger, but that would probably, at best, let the Bralwer keep even with most full-plate fighters or sword and boarders.
Still, I would have to say I prefer this version over the actual Brawler. With Brawler Skills, later books could add to the list, like they do for Rogue Talents and Rage Powers. It just makes it potentially more versatile.
