Borderlands 2: Mechromancer Pack Review (Internet Hate Machine)
The companion death trap is still buggy 10 years after release and the strongest ability in all of the skill trees (Anarchy) lets you get extra damage but less accuracy for reloads and stacks until 400 in total (if maxed). That means if you die you have to stack all over so retries on bosses or certain passages are essentially always more difficult and farming up stacks just takes ages, Also the reduced accuracy means you can not profit that easy from comeback kills, as enemies far away are often unkillable with a high stack count which is easily possible with a sniper rifle and a headshot on other classes.
Its a terribly punishing mechanic and I feel forced to play the build as its just superior too the others and I deeply regret making a Mechromancer as Main class
