But I win with Rivendare builds regularly. That woiuld be impossible if he was snped first 76% of the time. Beasts and Mechs rely on him heavily..
The thing here is that in the case of beasts, 1 taunt is usually enough to guarantee success cause that way you guarantee that your bird hits at least once and then with stuff like multiple (or golden) birds or wolf or by giving them reborn is usually enough for your comp to work and win games even if your Baron gets sniped immediatly after your one taunt dies.
In the case of mechs Baron can also be incredibly important but in this tribe he's usually protected by many taunts that have divine shield on top of it and some of them can even re-gain divine shield many times (deflecto and mecherel) so it's very rare for Baron to die early. The only cases I can think of being either your opponent having Zapp in which case bad luck and shouldn't be addressed in this study of sorts the OP is doing or is just straight up terrible positiong, in which case should be considered either cause it's player error.
