Are there any recharge slots in the powers or are you going 2 acc, 3 dam, 1 endredux? It would be easier if you simply said what you were slotting in all of the slots rather than just saying what you did with one of them.
No matter which slotting method you go with, you're not going to get a seamless attack chain with so little +recharge. That's one of the primary pitfalls of the low levels. You're just going to have to work around the waiting periods and learn to use with a priority list: Storm Kick, Crane Kick, Crippling Axe Kick, then Thunder Kick.
Currently lvl 29. Originally I had
Thunder kick: 1acc 3dam 1end
Storm kick: 1acc 3dam 1end 2rech
Crippling axe kick: 1acc 3dam 1end 2rech
The was reasonably smooth could go on indefinitely, but had gaps when I ran out of attacks. I decided to fit in Crane kick, which gave me more burst damage after buildup.
This resulted in
Thunder kick: 1acc 3dam
Storm kick: 1acc 3dam 1end
Crane kick: 1acc 3dam 1end
Crippling axe kick: 1acc 3dam 1end
At earliest convenience I am going to add in recharges. After picking up crane kick, my fights go faster...but then I find my endurance running out faster as well, and I get really annoying long gaps when I stand around staring at my recharging attacks.
The other idea I had was to pull slots from my secondary into the attacks and slot my armour in the 30s, when I get more slots. I have both dark armour and shield defense MA scrappers, both stuck at the same levels because of this endurance/attacks/slots problem. 
I'm not sure what's the best way to do things and thought I'd ask the experts... help me get my scrappers out of the doldrums!

I know this was posted before but it's been lost in time.
Can someone give me a decent attack chain that doesn't need a lot of recharge for MA, sans Eagle's claw and epics?
More info: I don't have hasten, not doing IO sets yet, keep 1 endred in my attacks (or I'll run out of endurance quickly).
