Anything else that is breaking the game in some fashion.
I'd argue that these are arbitrary rules.
Anything can basically fit in this category if you are technical enough.
Megalith reclaiming wrecks is not an intended use but it isn't listed here as a bannable exploit.
In fact, rule 3 is almost always broken by everyone.
Using unit interactions to abuse pathfinding
Can't block an ACU with units... that's a no no.
I apologize if I sound 'snarky' here, but, what comes next after this?
Do stealth fields only affect Cybran units?
Mobile shields only shield damage to units from their own faction?
What's the problem with mixing and matching a few units together?
It has never been a problem before.
These unit combos have been casted - and encouraged - dozens of times by well-known casters.
Gyle, Willow, Duelist, etc.
These are amazing plays and take time and multiple factions to pull off.
THAT is faction Synergy.
THAT is teamwork.
THAT is FAF.
Do not remove it.
