What determines if shift has to be pressed on a skill to target?

[Seravy]

I changed a few skills to be buffs instead of debuffs. The new effects work as intended but for some, I have to hold the Shift button to be able to target players as they default to target enemies. I want to change that to default to targeting players or if that's possible, target anything.

TargetType : Support is already set in skilldb_yml so I think this might be clientside, but I see no such setting in skillinfolist.lub, where do I find it?

...if all else fails, I can always play this class with /noshift on but would prefer to fix the skills instead.

Couldn't say without a bunch of testing but i thought al_heal was like the only skill that has shift targeting
