It doesnt matter which brawler type you play (stamden, stamcro, stamplar, stamdk) - if you are high skilled, you will rip apart zerglings anyway, but you will melt against duo/trio of the equally high skilled players. Is this correct?
P.S. In so called "PVP tier lists" one class is usually S tier, another A tier etc etc. But in reality, apart from duels, how much influence you class abilities/passives have for the outcome of Xing? Nowdays you have such a wide range gear/weapon or guild abilities to choose from, to compensate the lack of specific class skills (apart from streak and cloak)..
