It can be hard to balance all the many gameplay elements to eliminate loopholes... like FFVIII's physical (ie male characters') limit breaks. Not only do they allow a huge number of consecutive hits, but their effectiveness can often be doubled by using Meltdown to remove an opponent's Vitality. There is no equivalent for magic users - no multi-hit combo, no spell to eradicate Spirit. This almost requires the player to exploit the male leads' limit skills.

Opponents should behave in a more 'intelligent' manner, too. Take Lani from FFIX for example - she uses Scan to determine Garnet's elemental weaknesses, and then takes advantage of those weaknesses. She uses a variety of black and white magic, as well as physical attacks, in an effort to gain the upper hand. Unfortunately, she was often a miserably easy opponent. If a touger Boss used her kinds of strategies, it would greatly enhance the challenge. An opponent that'll pick on weak party members, analyze weak points, and basically avoid making the same silly mistakes repeatedly (like Ultimecia casting Holy on someone who's completely immune to that element) would add an extra element of thought and depth to the fights.
