I shoudo remind that with or without card and card skill your healing power doesn't change
While if you remove some abilities to the 2 others they are broken
And if we speak about sync
The one most hurt is the whm since 90% of his gameplay is suppressed by sync
Sch become hurt become he lose 75% of his healing power (less if EoS is rightly controled)
Ast on the opposite only lose a bit of his dps (ok nullify his aoe abilities) but stay fine
...
Any player blaming rng on card did not learn to use them because they all are great and have utilities in their current state
I fear the up incoming because it might be so great that... Well some people might cry

And nothing make a dps pants go wet more than a well timed card from ast rather than a whm no support
