Yes the gameplay is exactly like DotA becuase it is a moba game and is made by the original DotA Allstars creators.
The learning curve on it is very steep though. Learning the basics is a doddle, however to do well you need to know every champion's abilities, because any can be picked on your team or the enemies, the cooldowns on them, additional effects, how they are best used, when they will be used, how to use your own champions, when it is a good idea to go to a location, when to stay put and when to pull back, how to counter champions and item builds, how to work with the other members of your team and how to work in your role effectively.
Once you have played maybe 15-20 games, you will have a good enough grasp to really start enjoying it though. the biggest problem is learning the items and abilities though. Because you can't go and google them mid-game because it is non-stop and you can't pause or leave, you have to know which items you need and also how to deal with another enemy champion's build on the fly, as well as knowing the prices of items so you know when you can go back and get what you want to better know when it is worth going back.
=EDIT=
We have recently got ourselves someone in the clan who is a friend of a member just start playing. We have been playing with him and teaching him how. If you want to jump in too at some point should pick it up pretty quick with it being explained by at lest 3-4 people that have been playing and know the game
