Thanks for the feedback so far. Two quick notes - I am not the DM and suggestions for alternatives to the Flanking variant in the DMG aren't on the table. Also "I (don't) like it" is basically "this random person you have never met or come to value their opinion gives it thumbs up or down" - much more helpful are the ones describing why, like combat becomes more static or that unlike in 3.5 there is no cost to it.
But alternatives are helpful, IMO. When flanking is brought up as a possible rule at the table, is it not helpful to exemplify other ways that a DM can opt to grant advantage in combat? Especially since some/many others find these alternatives more fun than "I get on the other side of the baddie at no cost"?
Ultimately, you're providing reasons to your DM for/against flanking that you are harvesting from the internets. If flanking becomes a rule at your table, you'll all discover over time if it adds to the fun or not. You don't need us to tell you that.
