Pros
Pro Incredibly deep gameplay
For players who put the time into Dota 2 to get past the early beginner phase, Dota 2 can become an extremely satisfying game. There's a reason it's one of the most popular eSports titles in the world. The amount of strategy, skill and variables involved make it a very deep game where anything could happen.
Cons
Con Deserter status
Like many other team games with open matchmaking, it's both extremely rude and may carry real penalties to quit mid-match. If the whole game is in-office this isn't a problem, but if some players are remote they won't appreciate it if you suddenly have to get back to work.
Con Difficult to get into
Dota 2 is a very satisfying game, but only after hours upon hours are put into learning the games various in's and out's. Beginners should be warned that the game is very difficult and may not be fun for the first week or so.
