VERY slow debugging with Node.js + ECMA6 + angular-fullstack generater Follow

I'm working on a node project and I used "yo angular-fullstack" to generate it. This created a project that uses ECMA 6 syntax, so I enabled that in the project settings. Unfortunately, this seems to have slowed debugging down to a crawl. I found a reference somewhere to disabling js.debugger.v8.use.any.breakpoint and tried that and it helped some, but debugging is still intolerably slow. Any suggestions?

I'm using WS 10.0.4. OS X 10.10.5. MacBook Pro (17-inch, Late 2011). 2.5 GHz Intel Core i7. 16GB memory.

Any help would be greatly appreciated!

Also, does anybody know if angular-fullstack by default generates projects with ECMA 6 syntax? Mostly it's the import vs require statements. I'm wondering if there is a flag somewhere I can set to have it generate ECMA 5 script.

Thanks,
