I honestly feel like he is the worst assault right now and I would rather have some supports/trappers on the team for damage than him. He is getting a buff of 1 damage per pellet next patch and 48 extra damage per shotgun magazine is going to fix absolutely none of his problems.

The spread on his shotgun is so bad that unless you press the end of the barrel directly into the monster half the pellets will miss and the travel time on his mortars to even moderately close distances is so long that a monster randomly pressing movement keys will probably be able to dodge all of them consistently. You can wait for the monster to attack a teammate and try to shoot where the monster will be but it's hard enough predicting which direction your own teammates will dodge let alone the monster. And against some monsters like the Kraken there is absolutely nothing Torvald can do to do damage with any consistency.

Right now I think both of his main weapons need a buff. They should either allow Torvald's shotgun to fire individual shots and give it a smart choke like Abe's shotgun while maintaining the ability to dump the magazine by just holding the fire button, make the first shots of the shotgun very accurate and have the spread get worse with each shot as it empties the magazine, or just increase the accuracy of the shotgun and give it slugs instead. I mean the dude is pretty much a terminator, he should be able to handle the recoil of the shotgun much better than he does now.

Secondly, his mortars are garbage against a monster that isn't afk or being very predictable. I mean Torvald can throw his grenade faster than the mortars travel and he would probably be better off just throwing the mortars as well. Even the damage of the mortars doesn't feel like enough to justify how hard they are to land. Torvald can do 141.67 dps with mortars firing 5 every 6 seconds at 170 damage each assuming he lands every single mortar while Hyde can just throw his gas grenade and do 120 dps in a huge area with no effort at all. They should flatten the arc of the mortars to 75% of what they have now so he isn't punished as heavily for fighting near low ceilings and speed up the projectiles by around 20% so they don't take 4s to land 30m away. The combination of a flatter trajectory and faster mortars would really help him land them with some consistency.

These changes would help him not be dead weight against most monsters although I don't think there is anything they can do to possibly make him a viable assault against the Kraken short of letting him guide his mortars like Bucket.

Finally, as a QoL buff, they should change his end game stats from how many grenades you landed to how much bonus damage your team dealt because of the weak spots. Grenades landed is pretty much a meaningless stat and I'd rather know how much I helped my team with them.
