Dont get into dota 2 I have over 3000 hours and have been playing dota for about 9 years since dota 1. It will waste your life and will infuriate you after some of your games. Not to mention that the community is very toxic in general.
I will still play dota, but currently I wouldn't recommend new people to it. The new HUGE update is coming on the 1st, so if you wana try it out after nov 1 would be a good time.
