I'm not sure how hacks like self-revival/invincibility would even work because as far as I'm aware damage calculations and changes in HP are handled serverside and thus can't be tampered with.
The things they can mess with are things pertaining to movement and action delays, and the latter is particularly problematic when it allows hackers to output unreasonably large amounts of burst by dumping every OGCD ability in their kit on you simultaneously (And I have a hunch I've been subjected to that before...).
They already did that because people were ruining games of Rival Wings by using hacks to teleport the Oppressors above the objectives and bomb them from a height no one could actually reach.
