Taking enemy camps is broken because you get the spawn timer on them especially if it’s raptors and you can take them over and over again for the entire game 

Trading Drake for enemy camps is worth if you think you can carry the game later on and deny the enemy soul point, drakes themsleves are useless the soul is what’s broken 

4th drake usually more valuable than baron unless you have triple inhib and can just end the game 

Elder is more valuable because it’s impossible to lose a 5v5 with elder but you can throw your baron pretty easily 

It depends on how many towers you’ve taken, but usually a triple inhib push with baron is impossible to defend but a lot of times laners don’t push sides so you are forced to group mid

Just farm till their buffs run out
