Fairly solid build which overall for PvE play should do well. Things I would try to improve, particularly if one wanted to do "silly scrapper tricks" are:
1) Add some +To Hit in the build outside of BU type powers. This is one reason I tend to use Kismet +6% in many of my scrapper builds. Since Kismet is dependent on the power being active I typically add an 'extra' slot to Focused Fighting for the IO. I like to see my powers accuracy at 95% vs +4's
2) More net end recovery. You are sitting around 2.48 end/sec (with Perf Shifter included) which combined with inspires etc should be adequate most of the time but you will need to pay attention in longer fights to avoid detoggling yourself. I usually aim for over 2.5 end/sec and would be increasingly happy the closer I get to 3.0 end/sec or higher. Increasing net recovery some would also let you run Tough which you've slotted decently for +resist (a plus) so its a shame not be running it, but isn't included in your totals for consumption.
3) If including Elude for fun make it work for me when not using it. It takes several interesting IO's including Winter's Gift slow resist and LotG +7.5% that do not require the power be active (and are dependent on the level of the IO rather than power for function.)
4) Higher Max Health and higher passive regen both of which are to my mind the most important things to increase on an SR build after obtaining the soft cap (assuming reasonable endurance usage). More Health you have the more likely you are to survive the inevitable lucky (or sometimes not so lucky) heavy hits you'll take to either let your passive regen recover your health or give you the time to use Aid Self. Because of the presence of Aid Self this is less important for you than most of my builds (which usually do not employ the Medicine pool) but in just the sort of situations you might really be wanting to use Aid Self for more than topping off your health are also more likely to be the sort of situations when end use could be an issue (and spamming Aid Self is a potent way to eat your end bar and drop your dps ... of course being dead makes end usage moot and really hurts dps 
)
So this was my first toon to 50 and i really do enjoy playing him. Right now he does ok, but does take alot of deaths. Dont have a current build on him, but he is IO'd out (just not the best becasue i did it a while back). But i have come up with this build (with the help of a friend) and wanted to know if the soft capped melee, ranged, and AoE are enough to make up for the lack of res and lower def else where. I do like having the heal in this build cause on my one now ill be doing ok on dodging and what-not but if im outta greens, kinda helplessly standing there. And i did get to squeeze in elude (as a just in case, fun to have power). O and another thing that stucks out in this build for me is perma-hasten
So, if yall give it a look and have any ideas on it, let me know. Thanks
