Magic Transit is priced for the enterprise, out of reach for for a big chunk of the cheap VPS market: Minecraft servers and gaming in general, common DDOS targets.
Compared to other mitigation providers there were very few filters, and when you were under attack it just seemed to throttle your whole connection to as low as 50Kbps, meaning players would disconnect.
Magic Firewall exists now which is pretty powerful a la wire shark filters if I remember correctly. Otherwise MT filters are pretty good now. However I have encountered a few cases where a valid connection may drop depending on how sensitive your application is but pretty rare.
