Build / Gear combo while Lvling
I more or less used the same setup, I primarily used sword/focus first then my gs second. I would start fights out with mirror images then ileap to a target, blurred frenzy then shatter; if the mob was not dead then summon iwarden/izerker to finish the job with one attack cycle and if still not quite dead then use cry of frustration to finish off that last little sliver and if still not dead since you are in gs now and waiting for the ability to switch back can use the iwave to push the mobs away and then mirror blade/mind stab. Not saying this is the only way to play of course but I found it quite effective, sounds like alot of steps but once you get good at your skills can be pulled off very quickly, though I found up until lvl 70 or so not much surived after the initial opening combo and then a iwarden. Hope this helps some enjoy!
Have Staff with you all the time in solo PvE its a great weapon. Learn how to play Sword and figure out if GS is something you enjoy or not.
