uhh no? so if some dumbass decides to go tank should i follow his lead? instead of the smart carry that knows when to engage? some objectives are better than others, i won't go take the enemy blue/red if i can take an inhib. I won't go take random turret if i can take an inhib. I won't go baron when we are low after a fight with a non baron taking comp i much rather take a turret or back away. I won't go waste time with Elder Dragon when we are just going to end up wasting most of it by backing off when we can just take it when we are healthy and can actually use it.
If you call is dumb and stupid don't expect people to follow them, it doesn't matter if you are a tank, a carry, a support or god himself. If people don't follow good calls? that's a different story but there is no "we should just follow whatever this random person says" since his calls can be really dumb specially when his calls have been really dumb
