As many of you know upgrading walls uses up most of your gold. I was thinking of a way they could increase the importance of walls without making them OP. When you have all of the same level walls your health per wall will increase so if you have all level 5 walls and up ( so like 175 lv5 walls and 25 lv6 for example) you get a 5% increase in health for each wall and the increase goes up with the level, so all lv7 walls and up would give you 7% increase in health. It's just a bit of a bonus for when you FINALLY get all your walls upgraded and they could possible add in a tiny display upgrade when they are all the same level. Maybe the increase could scale up a little as walls get really hard to upgrade around lv7 and the initial increase could start at a higher level wall so u get the 1% increase at lets say lv5 , but anyway what do u guys think?
