I'm guessing you never played Tales of Destiny, Phantasia, or Narikiri Dungeon. That's what Tales of was originally. Personally, I found Symphonia's to be a mindless buttonmasher. At least in Legendia, you actually had to have STRATEGY, since your resources were limited. (Plus, Shwartz is more brutal then ANYTHING in Symphonia...and the cameo fight in the arena in ToS was nothing compared to the Curtis and Isabella fight. You WOULD lose if you weren't high enough. You could inch your way through ToS.)
I just perferred it over the whole...."BUTTONMASH LOL APPLE GEL".
Also, Legendia had another thing over Symphonia. SMART healers. In Legendia, when you tell Will/Norma/Shirley to save TP until you NEEDED the healing, they would SAVE TP. I couldn't count how many times it took Raine until I was at 300 or so HP before she would cast FIRST AID. Not Nurse to heal the almost dead Genis and Sheena. First Aid. On Lloyd. When I was out of Life Bottles. So here's the HP count:
Lloyd Genis Sheena Raine
HP1247 HP 0 HP 50 HP 258
TP 2 TP 53 TP 0 TP 4
I was battling Shadow, all of my characters around lvl 83. Basically, all healers are retards in Symphonia. Plus, they burned through TP like a motherfucker. I dunno how many times I was saved by Will/Shirley with Cure, and then they wouldn't spend ANY TP until just the right time.
