Your kit is rolled every battle
No unit ever fields its whole catalogue. Each ability rolls independently — 75% for a common down to 10% for an ultimate — so the army you brought and the army you command are different questions. Roughly one unit in 150 skips the roll entirely and fields everything.
So is your gear
Five slots, drawn fresh from 241 items across 19 weapon classes. There is no inventory, no shop, and nothing to grind for — a level-one account can roll the best weapon in the game. Account level raises the floor of the draw, never its ceiling.
Height and facing decide fights
Charge Time turn order, elevation, and where you are standing when you swing. Attacking from behind ignores evasion entirely, which is why flanking beats dodging — and why a dodge-heavy class is not simply better than an armoured one.
