I'm sincerely sorry to hear that you are disappointed in your results. Many users have seen significant increases in their earnings on Blaze and other auto-exchange pools with the Build Larger Shares feature enabled. For me personally, it has decreased my payout time on Blaze by a day.
I did a test of it enabled and disabled and it didn't really make much of a difference. I do currently have it enabled though.
That is why I invest a bit of development time in including pools that do not auto-exchange such as Icemining.ca and Quantum Mining Pool in Hash Auger even though most users prefer the convenience of auto-exchanging. Including support for the dedicated coin ports that more and more of these pools are using took some time as the feature is not currently supported by the Yiimp API. Yet, this provided Hash Auger users with greater flexibility. If you just wanted to mine just Raven, you could create a new wallet in HA with your Raven wallet address and then enable a few pools that mine Raven and do not auto-exchange. The software will then compare prices and switch Raven mining to whichever pool has the best estimate. Similarly, if you wanted to mine Raven and a few other specific coins without auto-exchanging, the software can switch among just those coins whether they are on the same pool or different pools. I've spent a lot of development time trying to make mining individual coins as seamless as auto-exchanging.
I'm not really interested in keeping a lot of alt-coins laying or spending time exchanging them manually. I have a small portfolio of coins that I HODL and Ravencoin is one of them. I was using HiveOS (Linux-based) before, nothing against your software, I would probably go back to that to avoid any extra developer fees. Hashrate in Linux was also a little better than Windows using Nevermore.
In fact, you can even mix the two types of mining in Hash Auger. For example, add a Raven wallet and enable a couple of pools that do not auto-exchange and then keep Blaze or another auto-exchange pool enabled. The software will switch among the work based on current estimates. However, given the volatility of Raven prices on some auto-exchange pools, you may want to disable x16r on the auto-exchange pool if you try this approach.
This approach would spread my rig out too thin. I find that if I'm not using the entire rig to mine on one pool only, then my profits really take a dive and it takes too much time to get paid out.
