Here is a thread where you can discuss your EBF strategies, how you like/dislike the game, about the upcoming EBF4 (I hope that it will be even more epic than EBF3), etc.
My strategy for the first main chunk of the game (EBF 3) was hit hard and fast, but towards the end I am tailoring the beginning of the battle to favor me living long and dealing hard damage.
Usually using Natalie's Regen with Matt's Protect and Lance either using Debilitate or Flare, with the next round Natalie either using Syphon or Barrier with the other two beginning the assault.
Then its hit hard and fast with rebuffs/debuffs coming in occasionally.
I don't have any strategies for EBF2, as I haven't played it very much. I can give you some basic strategies for EBF3, as I have passed it about 3 different times.
