It's been discussed quite a bit in the DPS section. We'll have to wait and see what happens in 7.0

The heal can go. Maybe they could convert it to a barrier cast.

Carb is traditionally meant for support, but the main reason it doesn't attack is because pet autos were one of those issues with the previous SMN build.

Some new summons would be nice, just for visual flavor. I wouldn't want to lose something like the gap closer in the second round.
