Why is the Burrito so ass?

1700 hours in, i love my 119 and i like to build the decks to be fun and to lean to the fun stuff of each div - so 119 gets spetnaz, super heavy tanks and the burritos for the memes. But bro why is the burrito so ass? Ive used it hundreds of times, ive been on the receiving end another bunch and its super random if it will do any damage. My towed arty gets waaay more kills every single time, and costs a fraction of the big turds. WHY?
