I honestly felt LoD's battle system was the saving grace of the game besides the music. It certainly wasn't the plot or characters.

BoF1 comes to mind, simply because it's easy to break the game and some of the boss battles pretty much require you to do so.

Arc the Lad trilogy also comes to mind. It lacks the heavy customization need for the SRPG genre and the units tend to be unbalanced making the end game a bit tricky since you've likely focused on five characters and left everyone else to dust. The vanilla combat combined with the genres "load and loads of battles" schlick will have you quitting out of boredom pretty quick.

Controversial one here, Chrono Cross. I appreciate trying to be something different and on paper the system sounds pretty good but elements always lag behind physical attacks with upgraded weapons and the AP system works against using them often beyond healing. Summons are a chore to use and obtain and the dual/triple tech mechanic is so poorly utilized, you wonder why they even bothered. I enjoy CC but the battle system is not one of the reasons.
