The problem with a team of Street Sams is that a hacker a few blocks over in a van could hack all their gear and explode them .
The problem with a team of hackers is that a mage a few blocks over still could summon a spirit to find them, go astral, and summon spirits into the van until the hackers die.
The problem with a team of mages is... another team of mages?
That's why I suggested the Attribute + (6- Essence) change. It'd help to put the answer to mages back to Street Sams.
