In a group it does not damage as much, however it always seems getting the monsters attention and tanking it. Now, you will be told a few times in game that Blademaster is not meant for defence, however, the build suits a style of play, and you can run into Blademasters with similar builds.
From here, it intends to raise the str, phy, dex and dur, with duribility being the main priority for the next level (Dream of Mirror Online Gold) or so. As far as skills, you may have not touched the martyr attacks, and have opted to spend points on the beastial attacks (saveing for thesabre armor for all classes skill)
Got them all effective provided you know what situations to use what in. Against something that does high dammage, use eagle shrek and fierce bark. To get a monsters attention away from team members use menaceing moo. Growling tiger is fun if you have a hunter/shaman in your team.
Hair raising hiss is always good as it lowers the enemys defence.
At the last you will feel a blademaster that adding durabilty became nessary as solo leveling progressed, as well as the need for healing.
