ZeronHitaro's ridiculous estimate aside (75,000 actions? Really?), the abstract attack animations have really never bothered me.
Is it that ridiculous? Let's look at one of the starting areas alone. The Kaipo region. From the walk from the western mountains, to a bit of brief exploration (In order to level up Rydia), to the cave needed to advance the plot I encountered roughly 15 battles (maybe a bit more or less, 15 seems like a good estimate).
Each battle in that region had about 3-4 enemies. For the sake of simplicity I'll just assume a 3 base for each battle. 15 battles x 3 enemies per gives us about 45 enemies total.
Between Cecil and Rydia it only took one attack from each to kill an enemy, not counting all the random variables such as "misses" or damage that was too low for a standard kill or high enough to kill in one hit. 45 enemies x 2 hits per = 90 standard attack actions in one little section.
Keep in mind, this is one of the smaller regions in the game. The longer you play the bigger the dungeons get, the more battles you fight and the more standard attacks it takes to kill a foe. I would bet good money that by the time you have reached game end the total number of standard attack actions is in the tens of thousands range. I will admit that 75K is a bit high but my point still stands. Adding on 2 seconds to an attack animation would accumulate into a respectable number by game's end.
