No but really, lol has a different meaning. Or at least to me it does. I use lol when something is actually funny, which isnt that often. L or l is more like something you add to the end of a sentence to make sure people dont interpret it literally. Like ehm while in a dungeon and some guy dies for the 4th time what, you died again? or what, you died again? l pretty terrible example but i cant think of something better atm. Basically the l is there to show you're not serious or annoyed or whatever
