Is it all worth getting into? [Inimidated]

Hey all! I was talking about Vainglory the mobile moba with my friend the other day and he basically said fuck that come play league. Having played Heroes of Newearth waaay back and more recently Heroes Of The Storm a lot as well as DOTA 2 until my computer died and having been able to get quite good at Vainglory its obvious I enjoy mobas. But I beleive in such a large game such as league of legends with all its champs im a bit intimidated by having to learn everything in it.. have I missed the LoL train? Is it even worth getting into at this stage in its life? Or will it be countless frustrating hours until im even a little above noob status?

Edit - Seems like a resounding yes from you folks!! Thanks guys I appreciate the input! Seems like a great community here
