What I think is important is to state the positive effects of intelligence in battle, vs. a higher attack. My main attack hero has 66 intel. I've read that 50 intel is good to have as it can provide a defensive boost against swordsman, or something to that effect. However, the next defensive boost specific to a unit is so high that it would be a waste increasing my intelligence further, to the detriment of the attack. I also read that the respective advantage of intel compared to attack, to an attacking hero, is approximately 1:10. So why add a point to intel, instead of a point to attack which has 10x the effect. So before advising people to increase their intel stat, I'd investigate the respective advantage of 1 point to attack vs 1 point to intel. An interesting post though for sure. Thanks for the work, and for sharing.
