Why? Symbiod in War..

If we can't use Symbiods in war, then why can you use them on Defense? It's stupid.

Because symbioids on defense, even r5s, are easy targets due to a lack of an sp3 and easily avoidable sp1 and 2s. Plus, the symbol is sort of a giveaway if you try to hide it. No evade, armor, buffs of any kind - the ultimate trash defender.
You can bring them in on offense, just don't get hit - like Corvus, except without being nearly as useful.
