Apologies if this is the wrong forum to ask. Been itching to have a custom done with that kind of premise. I wish the people at slimewave had a way to request customs (maybe they do and I just couldn't find it?).
So its like an analogy. In starcraft, the terrans construct using a unit to build, the protoss constuct by summoning thier buildings, amd the zerg units morph into their buildings.
In the same way, every producer has different processes and ways of doing customs, so they are each different in terms of capabilities.
it is physically impossible to go wrong with Jayce. I've done 5 with her and they've all been amazing. Jayce goes out of her way to make sure she's doing exactly what you want and knows all of the questions to ask to make sure all bases are covered.
