Philosophia is probably the perfect example of what we are talking about. Why ISNT it a party wide kardia. Because it isn’t it pops with regular healing actions as well as damage options, and you can’t buff it with soteria. The literal one modulation tool for kardia that SGE has and one that got a baffling CD reduction in this expansion

Literally one expansion in and they are already basically dumping kardia because they want everyone to be able to use philosophia

Then using your example of ET, sure the SCH has to think ahead and gets rewarded with potentially higher HPS but does that actually affect your decision whether to use it or not……..no you both just press it during a white hole/harrowing hell style mechanic and achieve the same thing
