Just curious what others think about this perk. I personally find it to be cumbersome fitting in all the gold units I want with the increased gold cap taken up. I feel like the perk would really shine if it added the units without increasing cap usage, but as it currently exists it is more a handicap than a benefit. The only unit where I feel this might not be the case would be blasters, as the extra 2 units per stack can help with maximizing damage while also maximizing hero space.
In fact, many people I've discussed this with just don't put the final point into T12 research to continue to maximize their cap efficiency. It just seems like a waste of a perk if people don't use it because the negatives outweigh the benefits.
