Any Class Help Advice for endgame builds (each class)

Hello, I'm getting back into the game after a while and decided to go with a fresh start, deleting all my lvl 100+ classes except for my original archer.

I'm looking for advice on what mythics I would use for each class depending on what sort of style I'm playing

For archer I'm currently using freedom boltslinger. Already set up

Shaman I'm using Tstack aftershock. Already set up

Assassin - undecided. Looking for glassyish spell spam build possibly using cataclysm. Usable for raids.

Mage - undecided. I heard riftwalker was good but never tried out dps mage

Warrior - undecided. I'm tempted to use thrundacrack (because it sounds cool lmao). Maybe going for a support type build

Maybe not relevant but these are the mythics I currently own:

- Very decent freedom
- decent ashock
- mid collapse
- mid Boreal
- very mid stratiformis

I'm not asking to go through the trouble of curating a build, just suggesting a mythic that would suite the type of play for each class I mentioned before.
