Overwatch – Balancing for Pro’s and Casuals, good or bad idea?

Overwatch has been around for a little over half a year now, it has gone through a number of balance patches and yet the game is in such a terrible state for balancing, it's quite shocking that a game can be this unbalanced when there are only 23 characters to take into consideration, while a game like Dota2 that has a little over 100 characters has much better overall balance.
