Total 4.6
A team full of replacement players should win 48 games, and would have 8.6 wins at this point in the season. Adding the Braves WAR to 8.6 gives a theoretical win total of 13.2. The Braves actually have 11 wins (due mostly to a horrid 2-6 record in 1 run games).
Seems to me WAR is doing a pretty good job evaluating player performance. I know some won't like that fact, but there it is.
The biggest trouble spot is the rotation. They have produced a combined non-hitting WAR of 0.3. That is bad news for a team that is building around pitching and just spent $35M to fill 3 rotation spots.
