How can you "break" out of immersion by something that is system-mechanic ... and therefore it dont even exists, from story (in wich you are immersing) perspective? O_o
Because role playing games usually have a coherent visual and narrative layer upon the "system-mechanic".
Immersion is the core purpose of role playing and such flaws in the systems break the immersion in "the experience" as a whole. You really didn't understand anything I wrote as expected...
And now you're repeating the same things once again. It's fine if your definition of immersion is more shallowed, you know.
