plz give me some advise

Get rid of sneaky or lifesteal and use fast reflexes. If you're lixing most of the time then dont use life steal. If not then I guess it's useful but I do recall it consuming a lot of energy.
Max--Shadowstrike, Riposte and Quick-strike. Dump the rest into fast reflexes.
More defense will come in handy because at your level most of the mobs don't use skills and you should be dodging half their autos or even more often than that. Are you still lvling on pirates? If so, try grouping 2-3 at a time then Riposte followed by the rest of your skills; Repeat this till they're all dead. Have some restos on hand just incase you get reckless and try taking on more than 1 4* at a time.
edit- post your HP/energy and the rest of your stats as well. Would be more helpful for anyone that wants to provide feedback.
