Sch Tips of SA1 (Help me to improve)

[Mirakumi]

So I need some help getting insight here. (I want to better myself.)

On most videos I've seen a SCH + WHM duo where SCH is aggressive dding while popping out for preys.

But then for my group the whm claims that he can't handle all that damage alone. That he needs me from start to finish as pure healing. So I get confused since friends with win say whm is possible to solo heal as long as I help on double pray and tank buster.)

Then I've heard that people have been clearing if SCH dps till split and heals the rest of the way...
Basically I just want to know what is the best way to approach this fight. (Furthest progression we've had is to 2nd jump me just healing (extra help on double prey/virus on non drk tank add)

Right now how we handle the fight is I handle the war tank and 2 dd on the south edge with him. When they get preys I handle them. if double whm assists me calling out who he will help. Vice Versa if double prey is on his dd.
Also have Selene out during first part -> swap to eos after.
