.You are right. However, part of the fun of such an expanded disease system would be trying to guess from the symptoms what kind of disease the character has, and give proper treatments. But this is only one system among many I would like to add, although this one wasn't in the lost continent 1, so I would have to think it and code it from scratch, which will be fun.
And INT will be important to all players, because with the learn from failure system (see TLC), intelligence is a big XP gain bonus. So an idiot won't gain XP as fast as a clever character.
