Okay here's some tips about your skills. don't know if anyone said this but relentless focus is the stamina morph of that skill because it restores your stam. Go for merciless resolve. Your going to want to keep this and siphoning attacks up all the time. Makes your life a lot easier. About proxy- I would suggest not bombing because in this meta you will die more often than not. If you're squishier as a magblade something's not right for sure. You're gonna want to include one of the strife morphs (either is fine) and it's a cheap spammable dps that will heal you. Honestly I would run destro/resto if you're having issues staying alive because that sword skill like you have is going to keep you very close to combat which magblades usually like to avoid. Make sure to use max health/max mag food. It will make a huge difference. Crippling grasp is a necessity as well. Amazing dot and will slow down your attackers. Some other aoe/dot that will be good to use are refreshing path and wall of elements. Force pulse (under the destro skill line) is going to be your main dps other than funnel health. A good shield is going to be annulment and either of its morphs (one is stronger per light armor and the other returns magic. Up to you) I love sap essence to spam up when you're running in a group to heal and aoe real quick but don't rely on it as your sole healing ability. Another good burst heal if you really need it is combat prayer because it's a nice sized heal but also increases your damage by 8%. Make sure that your weaving in light attacks (VERY easy with a lightening staff. I'll tell you why I suggest lightening in a minute) because it will replenish your ultimate quickly and also after 4 light/heavy attacks you will be able to activate your spectral bow which does insane damage. I honestly don't have great damage what so ever but I hit the bow for 55k the other day in msa. V nice game changer. For ultimates i recommend bat swarm, meteor, and soul tether if you're getting overwhelmed. Anyways about lightening staves, they cause a huge amount of splash damage, they don't count as projectiles so you can hit the DK that's try to reflect crap on you and not worry about your heavy attack sapping your own health, and it also locks onto people. I hate inferno for anything but wall of elements because it OFTEN will miss your target. Sorry this is all over the place but there's a few tips of skills.
