Ranged DPS, choose a weakness that would justify a buff

[Lastelli]

that right here makes me question if you understand the word "Average", if say just as an example dancer had a 300 dps variance completly down to luck of proccs, crits not included as those are a factor for every class

I understand how basic statistics work, but it seems to me that you're just severely underestimating how much DNC dps can vary depending on luck of both procs and crit assuming that the rotation is correctly executed (which doesn't happen at lower percentiles). Balancing DNC and MCH around the average means that DNC will outdps MCH by a good 3% at the 99th percentile and that's the perfect way to kill MCH. Given how reliant DNC is on crit, I wouldn't be surprised if by the end of this tier, when all jobs are BiS, DNC will lead by a significant margin at higher percentiles. Actually, we already see how many people think MCH need more damage because they don't bring enough utility (compared to DNC)...of course they're wrong, MCH shouldn't be buffed if other ranged are kept as they are now, but making DNC much stronger than MCH when they're a little bit lucky and much stronger when they're very lucky is just asking to kill a job.

Then there are the other problems I mentioned that you keep ignoring. Nerf BRD and DNC multitarget damage, take away curing waltz, improv, minne and other such skills, make it so that all three jobs benefit from downtime in the same way instead of making DNC op when there's a lot of downtime and then maybe we can start talking about single target dps balance. You think MCH is "too strong"? I suggest you take a look at fflogs data for ultimate, the content that needs a good balance the most because it's the biggest challenge in the game right now.
