2. Practically speaking, stinger appeals to people looking to gamble in small sample sizes. It's all or nothing; if it doesn't activate, it's not helping. If you're more focused on long term averages, it's probably not as appealing as something like exceed would be as a 2nd skill. But that doesn't really come up until you have more dual skills to choose from than can fit in your grid.

For thunder events specifically, going forward what you can look to reliably acquire:
March: Gluttony union event - one SSR that's Pride (L) that FLBs to gain Stinger (S), one SSR that's Assault (L) that FLBs to gain Exceed (S)
May/June: Mastema 2nd reprint - one SSR that's Defender (L) that FLBs to gain Assault (S), one SSR that's just Stinger (L)
August: Yato-no-kami raid - one SSR that's Assault (L)
December: Wild Hunt raid - one SSR that's Assault (L)
And then there's the orichalcon exchange that never gets updated. Amaru glaive being Assault (M)/Defender (S) is actually good if you can spare the ori and time. And there's a Assault (L)/Stinger (S) bow that can be maxed out for 4 ori once ever, but has low stats.
I personally think that you should automatically try to pick up any SSR that has two skills (with at least one of them being Assault or Pride) until the grid for that element has 10 such dual skill weapons. Afterwards is when I'd start thinking about it with more nuance.
