agree with DM this is a good start.
Train Jump and Tkl. When you level up put all your points in ST until you soft cap it.
If you can sell that piece of gear that has a point in stamina I would do that...if its a piece of advanced gear nevermind.
After you softcap ST put all your points in Agility and anything left over in vision till you soft cap vision.
Once you get Agility up to the next natural cap switch to speed...once you hit the next cap on speed switch to strenght.
rinse and repeat.
Lots of good ways to build a DE but the best ones Ive seen have this stair step build.
ST 70
speed 80
agility 90
This is just an example but you get the idea.
The best thing about this is you can play either LDE or RDE. Your DC will probably want you at LDE because of your ST but you could do well at both spots. depending on the comp your going up against.
