Rework Suggestion: B1 Battle Droid
Of course, the B1 Battle Droid is the essential unit of the Separatist squad; it is at risk of losing stacks of Droid Battalion if General Grievous is its ally, damaging counter-attacking enemies, or it gets inflicted with Plague from Mother Talzin and Merrin.
Regarding B1's Relic tier, I wonder why B1 gets Critical Damage and Critical Chance from its Mastery if the Droid Battalion Unique ability keeps it from scoring critical hits.
Here is my rework idea of B1's Droid Battalion Unique Ability:
Unique 2: Droid Battalion (Level 9 Omicron): B1 can't score critical hits or be revived. B1 has no Protection, 1 Health, and 100 stacks of Droid Battalion (+20 per Relic Amplifier level*), and can't be defeated or destroyed while they have Droid Battalion. When all stacks of Droid Battalion expire, B1 is immediately destroyed. B1 is immune to Damage Over Time effects, Plague, and Max Health and Max Protection changes.
When B1 takes damage, they dispel all debuffs on themselves and lose 8 stacks of Droid Battalion. At the start of B1's turn, they gain 3 stacks of Droid Battalion.
B1 is immune to damage from Lord of Betrayal in the Sith Triumvirate Raid, modifiers in a Conquest battle, and Unique and Leader abilities**.
B1 gains 10% Offense and Potency for each stack of Profit on it***. Whenever B1 would recover Health or Protection, it gains 5% Defense Penetration (stacking, max 100%) for 2 turns instead****.
Droid Battalion: Each stack grants B1 +2% Offense and all Separatist allies +0.5% Tenacity and Critical Avoidance
While in Territory Battles: B1 has 150 stacks of Droid Battalion instead and can be revived at 1 Health when all stacks of Droid Battalion expire. At the start of each encounter, B1 is revived at 1 Health. Additionally, B1 gains 50 stacks of Droid Battalion at the start of each encounter or whenever it is revived.
Whenever B1 loses more than 50 stacks of Droid Battalion, it gains Damage Immunity for 1 turn, which can't be copied, dispelled, or prevented (once per turn).
While B1 has more than 100 stacks of Droid Battalion, Separatist allies have 100% Defense Penetration (doubled for Separatist Droids) when attacking Target Locked enemies. Otherwise, B1 gains 3 stacks of Droid Battalion whenever it is called to assist when attacking Target Locked enemies.
*Additional stacks of Droid Battalion might compensate for the flaw of B1's Mastery, which provides Critical Chance and Critical Damage. Additionally, it may make B1 more viable for the Battle of Naboo Raid, as enemy B1s take bonus turns.
**Indirect damage from examples, including Staunch Reprisal and Steadfast Retribution modifiers, Darth Traya's Compassion is Weakness Leader ability, and General Grievous' Metalloid Monstrosity, makes B1 vulnerable of, therefore, losing stacks of Droid Battalion more than it gains.
***B1 can gain a stack of Profit from Nute Gunray, who forces enemies to use Extortion. Gaining Critical Chance and Critical Damage from Profit is useless for B1 with the Droid Battalion Unique ability, so it should have gained Offense and Potency instead.
****B1 could recover Health from Wat Tambor's Heal over Time (HoT) or under Poggle's Archduke Leader ability. With the Droid Battalion Unique ability, however, healing is useless for B1, unless it could gain Defense Penetration instead.
