Um ... okay. And if you have a table where the DM is TPK'ing you within 5 minutes every time, maybe you find a new table?
I'm wondering if you might not understood the point, or maybe don't have much experience with LTRs, or other social groups?
In a group situation (whether it's an LTR, or a group of friends, or a social club, or a gaming group), you don't always get YOUR GREATEST FUN every single time. Instead, there are tradeoffs. Maybe you really wanted Thai food, but everyone else wanted pizza, so you get pizza! And next time, everyone gets Thai food.
Maybe you love rom-coms, and your SO loves horror films. So you watch the occasional horror film, and your SO watches the occasional rom-com, and you both love Shaun of the Dead.
Heck, maybe neither you nor your SO loves cleaning, but you decide to do the dishes, and your SO decides to clean the bathroom (or vice versa).
Maybe you love the social aspect of D&D, and someone else at the table loves combat. Well, hopefully you both can have fun, and it isn't just social, or just combat.
Because the group fun (the fact that you're doing something with people whose company you enjoy) is great enough that you aren't concerned with maximizing your individual fun. Or, put more simply- it's more fun to do things with people, and that fun is enough that you are willing to give (and get!) when it comes to individual fun.
