I would say try it so long as your resign yourself to the fact that, if you have no experience with MOBAs (multiplayer online battle arena), you're going to suck at it. No one is a natural at MOBAs, they place a very different emphasis on game mechanics (namely dying) than most games, and also require experience to know when you're in danger and when you aren't. However, myself and millions of other players find the genre to be one of the funnest genres out there. You'll catch on to how the game works, then start being able to employ that knowledge, then start being able to abuse it.
Don't falter if I make it seem intimidating; it's really not. It's just a hard genre to get into if you get frustrated easily. Though, I got super-frustrated when I started playing Dota the first time, but instead of deciding to stop playing I decided I wanted to kick the game's ***. Now almost all I play is MOBAs.
