Verso burn build comparison between Corpeso and Confuso

If you want to play a build where you want to stack as much burn as possible, there are two choices :

Corpeso : basic attack gives 2 burn per rank, stacking combo attack and double burn gives 80 burn, you can also add burning shots rewarding mark and marking shots to get on average 4 extra burn (20% of 9-11 shots and double burn). You can finetune it (with beneficial contamination for example) to get some more burn but let's take 84 average burn per turn

Confuso : critical hit on light damage gives 1 burn, it works on free aim shot so you would get 18 burn. you'd also get 6 (3 times 2) burn per mark which works with marking shots and 2 burn per burning shot. which in total gives on average 34 burns, then we add the extra 8 maximum burn from basic attack and we get 42 burn per turn on average.

Now confuso could potentially be better if we had a way to apply mark 7 more times, which I didn't find. Also the fact it turns mark into burn stops rewarding mark from working. Double mark and stay marked doesn't have any interaction as far as my testing went.

So it clearly seems that Corpeso is strickly better than Confuso for what both weapons try to achieve, And it's a bit sad because I feel like Confuso has a lot of lost potential and the way it applies burn is more satisfying to me.
