split pushing and hand of baron

so as i reading through the patch notes i noticed a decent solution to the split push issue, until it reached hand of baron. my issue is that even with the turret buffs defending, this would result in split pushes that are similar or worse than the split pushes before becuaes the minions would give a massive boost just due to the presence of one hero making it difficult to defend. it should be that there has to be at least 2 or 3 heros within a 2500 radius or 2000 in order for this minion boost to work
