There is plenty of grind content where you can take a job with a complete action set and grind for hours if you want. Not everyone enjoys a meaningless grind.
Mounts and outfits do matter, and if you want to spend time playing with major holes in your rotation, having to end combos after only two steps, with large amounts of time spent not pressing anything except 1, there are places you can go while the rest of us focus on how to play jobs that have fleshed out rotations.I guess people don't think it matters because they like hand outs when it comes to things that matter, but will work for stupid mounts and outfits/titles lol
