I actually thought that it would be hella cool that if they just embrace the whole "Inaros has no ability and is a literal sand-filled punching bag with immortality" and just remove all of his active abilities and give him "trigger" abilities that activates in specific scenarios.
Passive: Health gating - Inaros will always survive lethal damage with 1 HP and have 2 seconds invulnerability. Inaros only gets downed if he took damage with only 1 HP. If you play Kingdom Hearts, you know how it is (can maybe have cooldown for balancing).
Trigger 1: Cooldown 5 secs, at 75% health, release a radial sand blast that stuns nearby enemies. Perform finishers on affected enemies to restore HP
Trigger 2: every 10th enemy killed, creates a sand clone of Inaros for 15 secs. Similar behavior to Wuclone
Trigger 3: Cooldown 30 secs, at 25% health, releases a sand tornado that pulls in and ragdolls enemies for 2 seconds, then persists for 10 seconds. Damage scales with melee mods. This way, enemies are gathered in the middle of the tornado and is susceptible to headshots
Trigger 4: every ability triggered will increase Inaros' armor by 3%. At 100% bonus, each ability triggered creates a sarcophagus that heals nearby allies and releases a scarab swarm that stuns enemies. Only 2 sarcophagi can be active at the same time.
Subsumed abilities work on Inaros by consuming HP at 10x the energy requirements. 25 Energy abilities will use 250 of Inaros HP.
This would preferably come with enemy threat perception rework. Basically, the "glass cannon" frames have trouble with surviving in high levels and have to rely on shield gating. This system rework will basically make enemies prioritize players with the most max HP. Thus, Inaros will have more abilities triggered with this new system and also reducing incoming fire to players with less HP.
I imagine with this gameplay, we just need to focus on mowing enemies down as the abilities will automatically activate to make our lives easier.
