Looks decent maybe fit hasten in there somewhere probably instead of hurdle but you have 4 single target attacks before 20 so you much better DPS than most scrappers that level, probably only dark has more.

Ugh, Jump Kick! 
Regen slotting looks alright (the worth of the EndRed in Integration is debateable though), but attacks really need to be 6-slotted - I prefer 2xAcc, 3xDamage, 1xRech without FA or 1xAcc, 3xDamage, 1xRech, 1xEndRed when you get FA.
Take those slots out of Revive, it only needs the base slot (if you take the power at all, I find an Awaken is plenty) and the same goes for Swift and Super Jump. Put those slots into your attacks.
What level are you? At level 50 you will have too many attacks, I find that slotted with 1xRech Thunder Kick, Storm Kick, Crane Kick and Eagle's Claw chain very well. Crippling Axe Kick is a good power to have till 32 but the awful animation meant I respecced it out as soon as Eagle's Claw was slotted up.
I didn't take Cobra Strike until 49 (I had nothing else I really needed), Regen will provide you with plenty of defence and I never found I desperately needed to mez a mob. Sappers can go down in a couple of hits before they can react to your presence.
You really don't need Conserve Power with Quick Recovery and Stamina.
For reference, here is my MA/Regen build:

Hope this helps.
Thanks for the responses so far guys, it's been a big help. Won't repost the build - think I have enough to go on by myself.
I'm only level 7 at the moment, but I played a Claw/Invulnerability to level 41 and enjoyed her immensely so I can see myself going the same distance with this Scrapper as well.
The problem that keeps poking me in the back is balancing my accuracy and recharges (which is why I only have four slots in my attacks with the original build). I take it I'm not going to notice a huge decrease in survivability if I trade some of those early defense recharges for an extra accuracy or two? Early on at least.
Thanks again for the help.
Yeah, early on I give slotting priority to my primary over my secondary and mainly slot accuracy as in the lower levels the best defence really is a good offence.
That settles that then, heh. Pushed back the recharges a little to slot out my attacks earlier - think after these changes I have a very solid build.
Thanks for all the help!

To me it looks pretty solid, but I'm a little worried about the pre-20 DPS, heh.
I've been thinking of getting rid of the fitness pool and jamming in stealth - more for concept than anything - but beyond that there are no powers I'm after in any massive way. And no, I refuse to give up Jump Kick. I think it's awesome.
Not sure what else to include, so....thanks in advance?
