General talents
-healing totem is a decent option if there is no specifick talent in that tier.
-if you can take clense take it. Cleanse is a number 1 pick for supports. Dont get cleanse if it doesnt work for your final build.
-storm shield is a good level 20 pick if the heroic upgrades arent really good.
-if you notice that the backline continiously gets dived. Dont hesitate to pick bolt of the storm to get yourself in safety.
-rewind is a good option for your hero if you have low cooldowns or strong abilities.

General strategie
-save soak lanes when solo laning. There are some exceptions like Tassadar.
-when soaking lanes with 1 or more teammates in lane stay behind you teammates.
-stay save behind your frontline and you want to be in like 90-100% of all teamfights.
-make sure you or your frontline is save before healing your backline.

Goals
-when first playing the support role. Or when practicing the support heroes make sure you set goals for yourself for each game you play.
-A goal of mine evrytime i play a support hero i want to get atleast 30-40k healing.
-or to die < 4 times in the entire match.

Playing the support role learns you alot of positioning for the other roles. Because as a support you have to play a bit saver but you die less. this can help you when you are playing squishy assassins and/or specialists.
In my opinion everybody taht wants to get better at playinhg HOTS has to learn how to play as a decent support.

the other chapters will go more indepth about each single hero.


*The hreoes are orderd in tier rank. So malfurion is now (2 dec 2016) the best support and tassadar the worst*
