It’s time to show Kruber some love in general.
Kruber is the character we play in the intro, so he’s the first character every single new player is exposed to. Further, he’s the pre-selected, leftmost, default character once you actually start playing the game, so he’s a lot of players’ first choice. He’s also, across all three classes, extremely clunky at the best of times and is now the most underpowered character overall, even in the hands of skilled veterans, and he lacks the functional tankiness to make up for it. As such, a lot of ppls’ first exposure to multiplayer is going to be extremely lackluster.
Having any one class not be as smooth, polished, well thought out, or fun as it should be is a big deal. Having an entire character suffer from this is an even bigger deal. Having the default and poster-boy character have this many problems and such a prevalent identity crisis on all three classes is catastrophic. I have witnessed new players ragequit over how unfun and unbalanced Kruber is to play unless you know 100% exactly what you’re doing with him and play him flawlessly at all times. Almost everything about every Kruber class and weapon needs to be looked at.
I don’t know why but you’ve taken everything that made him remotely competitive with other classes and removed it. It’s time to pay him the attention he deserves.
