@KKytes I don't know if this is included in tips or what but I recall that having OE+ Unit in one squad especially with the same Element can boost your All Parameters crazily by passive count. Of course, it's for those who were like grinding too hard/diligent enough to get OE+ Material that is. I think you should wording as "OE+ Unit is needed?"

One more thing, I think the position is needed too to make a great certain application of Cross Spark. Elemental Paradigm might be great for those who had OE+ but before that really even exist, there's one buff that people forget and it's from JPBF about X Sparks. As you all know even though there are only 2 Units who got that X Sparks during the battle itself, the buffs of X Sparks still applied to everyone else and it's counted by how many Units that had the same Element.

I think you should give Fei and Fang more credit due to themselves can easily apply X Sparks and because the counting is always by Element, it makes them more useful than the rest of them due to the easiest part to do X Sparks.

In case you didn't know, 1 X Spark from Fei and Fang that they're doing it themselves worthed +10% if the case was only them to be the Earth Unit, but if there's a full Earth Mono Squad, it will be +50% to All Parameters, plus they were like 90% - 100% chance to activate X Sparks so yeah I think you should give them more credit.
