What does the lightning bolt on Fortnite mean?

Yesterday I leveled my hero at Fortnite with these EP plates at level 8. Then also this lightning symbol (next to it is a 4) rose to 8. You can see the symbol in the top left corner.

I would like to ask what this means and why I'm suddenly back on BLitz 4, whereby this morning at 2 o'clock in the morning I was still 8

That's your overall strength

through your survivors in your team and through the research points and your hero, I believe so too. Flash level so starchy

So the higher the flash level is (the top of the line), the faster it works?

The faster you want to play through the game? You could also play through the game with your friends, which increases your blitzlevel and allows you to play the missions that are allowed from a blitzlevel earlier. If it does not work right now times try to make your lobby private in some must be so.

and I've always leveled up my survivors so I could get through everything quickly. Whether that's the best idea I do not know. Ask for the best in a community but be warned that will be a bit angry if you want to play through the game very quickly: /
