What you gave me is a nightmare, what your asking with that build is a nightmare. You picking stuff that's not meshing well. You wanna blapper, but you wanna use DP also.
Here is a build, I'm even not exactly happy with it. But it soft caps S/L Nearly Soft Caps E, and High 30s to low 40s for positional. It also offers decent bonus to recharge, but overall. Folks REALLY should D/L Mids and tool around and learn. Then play those builds and learn and re-tool, etc.. You'll start to see oh this doesn't work with this or that doesn't really go well with what I was thinking. Folks see all the flashy powers and want them all, but then want to live 24-7 as well. Especially as a Blaster/Blapper. You'll learn you have to sacrifice a lot of one way to go another.
