New SCH questions (Please help)

[h0tNstilettos]

I recently decided to start playing SCH as I was tired of SMN after maining it since it came out, plus I dislike SMN as an endgame job. I just got DRG to 50 and plan on having that as my other main. I want to use healer or tank for building up poetics and soldiery to gear my other jobs geared due to quick queue times, so I chose SCH over my level 37 WHM since it's already at 50. I still need to do my level 45 and 50 job quests.

My questions are...

1. How exactly is SCH played? Do I just do it the same as WHM and heal with Cleric Stance off and DPS with it on? Rotations? I already have the cross class skills such as Cleric Stance. I saw a video that said something about if the party member's health is above 80% you use a certain healing spell, but if below 80% you use a different one of the multiple healing spells.

2. How exactly are the pets used? In a video I saw that Selene is preferred for 4p dungeons, and Eos or Selene for the easier raids (CT), and Eos for harder raids (Coil Turns). I know there's a fairy thread here on the forums, but it assumes you already know the basics, so a lot of the stuff in it was confusing me. Do the pets heal automatically or do I have to target party member and manually use a pet's ability? I know they heal me automatically.

3. Why are macros a must for SCH? I heard one needed for cancelling pet's abilities. Why can't I just heel or steady like with SMN pet? I would hate to do my first party duty as a SCH and have it go disastrous because of me. I do have multiple macros on my SMN, but these are more for saving space on the hotbars and convenience.

4. I have never healed endgame before. One thing I always wondered is how does a healer keep party members healed during raids when everyone is spread out so far apart? I ask this due to my experience as a SMN when I would try to Swift Res a fallen party member, but they aren't in reach, so I have to look around for them. I imagined this same scenario if I was a healer trying to heal someone.

5. For Leeches and removing debuffs, how do I know what's a debuff and what isn't? I use PS4 controller and no mouse, so I can't mouse over a status effect to see what it does. I recognize some status effects by their symbol, but others I wouldn't know if buff or debuff. I know what poison, slow, and heavy look like.

6. Should Sacred Soil only be used on mobs and certain boss abilities where you know big damage is incoming, or every time available?
