need suggestion to progress the right way in the game.

You'll level just fine doing dungeons and the MSQ.
Dungeons (especially with their guaranteed drops) will also keep you geared enough to make it to endgame. There you can upgrade your gear further with tomestones which will get you through basically all content.

Next to your name it says you're level 51. So you've just unlocked Tomestones of Poetics.
At level cap 2 new kinds of tomestones unlock. They're collected and spent in much the same way Poetics are, as Poetics are used to buy gear from previous expacs endgames (among other things).

If you want the best gear though, yeah you'll need to raid.
