Hey, welcome to the club, looking forward to seeing what you can produce.

As for Illusions and Perception Alterations, it can actually go both ways with slightly different results for each. For example, my character is a master Outsorceror that can use a combination of fire and water moisture to create illusions, or most of the elements to simulate pressures on the skin or otherwise muck with a person's perception.

On the other hand, an Insorceror's manipulation would, as their name suggests, work entirely within the target's internals. They can create surprisingly good illusions of whatever they suggest the target would be seeing, or they can mess with the brain directly to alter sensory perception. 

Ultimately, it's probably easier for an Insorceror, but still possible for an Outsorceror. The one part that's easier for an Outsorceror, however, is that they don't have to create an illusion or alter the perceptions of each individual they want to target, as their illusion is a tangible object out in the world, or sounds they make to trick an enemy are actual sounds being made in the real world.
