Good report

Trying to get crossfire on the Reaver can help as it gets -1 to it's save then. Your list looks a little light on AT firepower, though the BA list is, so I guess your best option is to try to assault. Maybe a Terminator formation with Chaplain could be an idea to take on a titan.

Did the SW Great Company have its infantry touching vehicles for cover when the Baals rolled them or was it just bad saves that cost him?
Yeah, that's good practice for any infantry with AV transports in Epic. Having them touching the vehicles means the infantry can use them as cover and get a -1 to hit plus the vehicle doesn't loose movement having to scoot around a little bit to pick them up (in epic the vehicle moves to pick up an infantry stand by touching it not the other way round).
Baal's have ignore cover on their heavy flamers, so they would ignore this -1 though.
The Epic cover rules are deliberately generous and with area terrain like woods infantry only need to be touching the cover to claim the -1 and cover save. If you want to move the formation during the game it's better to have the infantry touching or partially in the cover, but not fully inside. If the infantry are fully inside (such as they look to be in
this photo) their vehicles would have to take a dangerous test to enter it to touch them and pick them up (don't need to test if the infantry are only partially in as the vehicle can touch them in the open).
Just mentioning to help for future games.
