Hahahahaha,
I don't have much to say about this one.
If you don't like being competitive, never, ever, ever, ever sign up for
the Beta/buy a Beta key.
If you don't know how every hero works, you're basically bending over for
anyone to take you.
Hey, don't get me wrong, it's a great game and I like playing it. But, it can
really get you angry, which is why I don't play it too much.
The music is great! The game play is very fun and it may be confusing at
first but once you play a little more, you will eventually learn how all the heroes
work.
I advise not to stick to one hero for too long. Especially if you're up
for a challenge and you start trying different modes (Captains mode, Random
Draft, etc...)
If you're stuck to one hero and that happens,
your hero may be picked off the list or you'll have a bunch of heroes that
you've never played. Either way, it's not a good situation for you.
Although, if you've never played that hero before but you've been on a
team with that hero or against one, it shouldn't be too bad. And sometimes it's
pretty fun to learn a new hero out of nowhere. I just advise learning the
basics.
Yeah, dota has a pretty steep learning curve. I would suggest playing against ai starting out, in order to learn the basics and get comfortable with a few heroes.
