**There is a mission which goes like this:**
_" 0/1 Reach level 6 by the second Shared Draft (Round 11)"_
Why would you want to lessen your chances to win?
This causes you to lower your income by not getting invest money.
If you have had bad RNG with heroes you don't want to invest gold to have another shitty hero on board, because
you lose your lose streak because of 1 round and most likely lose everything after it because you get less gold for winning.
If you have had good RNG you don't want to waste gold because you want to get fast as possible to 50 gold because it is more important than win streak.
It is like boost of adrenaline which causes you to die.
