Baron doesn't feel like it's worth it.
The only time Baron is feasible is when
a) Most or all of the opposing team is dead b) Your team has secured one or more of their inhibitors, forcing the other team to play defensively. c) Your team has the lead (risky - ish)
But during this time gap, wouldn't it be better to push instead? Baron is never a guarantee you'll achieve victory, taking all the turrets and nexus is. Baron steals and cleanups are also common in higher Elo's.
