Nah, this pool is great. I was dealing with the quirks of multiple coins manually. That was an headache.
That said, there's one thing miners will have to consider. When switching coins, the connection is interrupted for some seconds or no work is available. You must take into consideration what those 50+ daily start/stop cicles (and so, temperature variations) do to your videocards in the long term, specially if you're using --auto-fan. If you mine here, I suggest you undervolt, don't push them too far or take a serious look at cooling
