There are 4 types of hero
each type has 5 different characters to choose from, there IS NOT a set of characters required but certainly a good composition will help your team! (for example a troll team may pick 6 of the same character and still be able to win)
the best thing about blizzard is they keep adding things like maps and balance changes too keep the game fresh and most of all fun!
As a break down each char is completely unique and usually has a 2 abilities and if your lucky a passive also( one has wall ride passive) and each charter has an ultimate ability, you see Pharas ability in the video where she unloads a skidougal amout of rockets out in a short amount of time!
i dont want to overload this post with information so as a taster i have 3 videos to show you...
Phara - very similar to the robot chars from ut2004, equipped with rocket launcher and great mobility with jump boost ets
Genji - a ninja that looks exactly like greyfox from metal gear solid ( the guy who defect bullets back with his sword) uses shurikens as normal fire and has melee attacks too, his secondary ability can reflect all projectiles back where his is aiming!
Reinheardt - This is a tank with alot of health, a shield barrier and a massive hammer!
