Breakthrough still needs a drastic rework

In an update since the beta, it was mentioned breakthrough was getting rebalanced... What rebalancing was done, exactly? It's still the same issue as before. Super small capture points that are exposed from all sides, with the defenders getting a height advantage on most of them. Combine that with smoke grenades being locked to only support, and it's become even more difficult to attack. I see defenders winning 90% of the matches. I'm afraid for most maps, breakthrough needs to be reworked from the ground up. But as a starter, give everyone access to smoke grenades again. 

I'm having a lot of fun with the game, but this is one of the most glaring issues.
