First pick these if possible.
Strong picks on the map, usually to be selected around the second or first rotation. None of these are really ever wrong picks on the map.
These either are not on the power level of tier 2 heroes, or have little synergy with the map itself. These heroes are usually shown at the end of the draft to counter the enemy's team composition, or around halfway.
These guys tend to have anti-synergy with the map, or are just overall on a low power level.
I am the reason people don't get nice things
