You do know the Ukrainians have lost less then the Russians and that is what matters?Problem is they've been losing a metric butt ton of troops as well since the Russians are much better with close in urban meat grinder fighting than the utterly catastrophic complete wastes of men and material they experienced trying to assault Vuhledar.
The UAF might've much better served doing what they're doing around Vuhledar in giving up the city and letting the Russians charge across those open fields to the west of it again and again while they just rain artillery and replace mines... because if Vuhledar is any evidence, the Russians would do just that. They'd lose less men and thus be in a better position to counterattack into the city when they'd truly exhausted the Russians.
Besides the fact the Russians are using wave tactics to wear down the Ukrainians. Not normal assaulting it.
Also, Bakhmut is just trenches now as the city is just rubble
