I have been playing as a Bladedancer since I hit 15 as well and I am pretty much maxed out, just keep in mind it is a high-risk, high-reward type of game style. If you're not good with high-traffic and faced paced melee attacks this class isn't for you, all of the skill sets are melee and escape based. Activate your super, do as much damage as possible to as many people as possible, and get the -blam!- out of the range of fire. Very effective to clearing large hoardes of enemies in PvE, though in PvP, keep in mind Titian Defenders can survive your super even when maxed out. Be observant, pick your battles wisely and most importantly know your limits, arc blade is one of the strongest moves in the game. For now, focus on getting to level 20, and buy yourself some purple armor or blues with +light, you need all the defense you can get for this move.
