Honestly, I wish everyone would take this advise of yours.
The reason we have so much homogenization now is people complaining. Something about their Job is clunky or weird to use, some other Job has something they want, etc etc. Over time, that leads to everything being pushed into a homogenized slog.
Fact is, we've had Jobs that were distinct and interesting. If people would stop complaining, it would stay that way or be more that way. Yeah, it sucks when you like the aesthetic of a Job but you personally don't enjoy playing it. In an ideal world, every Job would be where it matches the aesthetic, so that people who like the aesthetic probably enjoy the playstyle (e.g. if there was a Thief/Rogue Job with Greased Lightning giving that feel of a really fast, nimble attacker), but sometimes that just doesn't work out.
The nice thing is, we have a lot of different choices, and there's always glamour. Maybe you like BLM's big elemental attacks but don't like the DoTs and procs. There's RDM sitting right there waiting for you that might fit you better, and you can always wear BLM-ish glamours with pointy hats or the Vivi Dwarf helmet cosplay and RP as a THM that learned all kinds of elemental spells to master all the elements like Ang from Avatar.
Point is, people should recognize that different Jobs NEED to be different, otherwise we have a morass of homogenization, which is ultimately boring for everyone. If you really really don't like the way a Job plays, look into some nearby Jobs for one that plays more to your liking and give that one a try. Glamour is magic, (no, really, in lore it is.

), and more people can be GENERALLY happy. The last thing we want is every Job playing just the same exact way.
