What can i use to record my own games? or gameplay?

I use Overwolf, but you can use OBS or Fraps etc

I went and played a match and refreshed the page and this was reposted right on top XD

Anyway, like I said before, I use BaronReplays.

Replay apps like that save spectator data, which are very small files, and you can rewatch them as if you were spectating the match. If you record raw footage you can use FRAPS or whatever, but the files are huge and you'll only see what was on screen at the time. I suggest you do both; you can run the replay recorder constantly for every game, and choose when you want to make a video file out of it.

I use Action! for mine.

I like to use OBS, it's pretty good
