As we all know, Chinese is very short of heavy infantry, and anti heavy infantry firepower is extremely surplus, so “mercirontroop” actually has some positioning conflicts for Chinese, so I suggest changing “mercirontroop” into a heavy infantry unit, making it a heavy infantry that Chinese needs to pay extra to manufacture, so as to make up for China’s anti cavalry weakness.
In addition, add a time 4 card to “Changdao” to enable it to acquire AOE capability. Of course, the cost of this card is that it costs money and will increase the cost / moving speed / population of “Changdao”, so as to achieve a balance. This can be used as an interesting PVE or entertainment card.
