Reworked how All Pick works in Ranked Matchmaking
Picking starts after a 35 second strategy period.
Teams alternate picking. Whenever it is a team's turn to pick, anyone on that team can pick for themselves.
Teams have up to 30 seconds to pick a hero. If the timer expires, each player that hasn't selected a hero will lose 2 gold per second. The selection will stay on this team until a hero is picked.
Once a selection is made, it immediately switches to the other team to pick.

Additional Notes:
Initial starting team is random, but known at the start of the strategy period.
If a team has not picked and continued losing gold for more than 30 seconds, a player that hasn’t picked will be assigned a random hero and the turn will resume to the other team.

Damage Type Changes

A few abilities and damage type mechanics have been reworked. There are now three primary damage types and a Spell Immunity Piercing status with each. Each ability now carries a notation in the tooltip indicating these.
The three damage types are Physical, Magical and Pure.
Physical is affected by Physical Armor, Magical is affected by Magical Damage Resistance and Pure is affected by neither.
Magic Immunity has now been renamed to Spell Immunity. Spell Immunity only defines if Spells interact with it, not how damage itself is handled. This means that on its own Spell Immunity status does not reduce any damage.
Black King Bar, Repel, Rage and all other previous forms of "Magic Immunity" now grant Spell Immunity status and a 100% Magic Resistance bonus.
In the vast majority of cases, the interactions are still the same, however an example of a case that would be different is if an ability has both Spell Immunity exception and has Pure damage type. Previously the damage would not have any impact, however now it does.
Ability Tooltips now have these fields:
-Damage Type: Physical/Magical/Pure
-Pierces Spell Immunity: Yes/No
If the Damage Type is not Magical it will be colored differently to make it easier to notice. The same is true in cases where Pierces Spell Immunity is Yes.
There have been a few abilities rebalanced with these mechanics in mind. In some cases the intent is to maintain similar balance, in other cases as an adjustment to their balance.
