Brawler - cont.
Because the brawler profession is such a specialized profession, it makes sense to not only operate as a brawler, but as two or three other professions as well. The one profession that probably works best with the brawler is the scout. In fact, it is almost essential that you are a good scout if you want to be a good brawler. As a scout, you will be able to travel more easily and get more of a reward from killing animals (scouts can harvest bone and hide from dead fauna). Even more importantly, when an enemy runs away from you, you will be able to catch them more easily using the skills from both the brawler and the scout. If you also include the medic or entertainer profession then you will be able to be quite self-sufficient, unless you are looking to buy any items, at which point you would need to include the artisan line of skills.
All in all, the brawler, like the marksman, can combine pretty well with any of the professions and prove quite useful. The only profession that the brawler does not combine overly well with is the marksman. Combining those two professions really just doubles up on combat skills, which is inefficient when you can only increase one or the other at a time. As a result, you would progress more slowly in your combat abilities.
Because the brawler in a group is normally considered the tank, you will want to be the player who is always trying to put yourself between your group and the enemies. In other words, continually charge the enemies, draw them back, and let the rest of your group pelt them with ranged fire. Naturally it helps to have a good medic in your group when doing this.
If, on the other hand, you are playing as a loner, then you will want to be a bit more careful, and in-between battles make sure that you take the time to rest and recuperate. Otherwise you will suffer in any subsequent battles.
Additionally, when playing as the brawler you will want to make sure that you choose stats which are as balanced as possible. Many people tip their stats heavily in favor of health, thinking that the more they have, the more they will be able to take. This is not how Galaxies works; an enemy can target any of your stats depending on their chosen method of attack. If your stats are skewed too much in any one direction you will be easy pickings for quite a few enemies.
