Upgraded 2 lvl10 walls and 1 lvl11 wall today.
Started the upgrade of 1 of my cannons to lvl13 today, not sure how much impact it will really make but I need a free builder 7 days later so that is more important.
Tried out miners today and they are absolute garbage. Without the warden adding 275 hp, they are simply too slow and too frail to do anything. Bringing 150 barbs may be better than using 30 miners at this point. Warden will max at 1st March if everything goes to plan and I hope to be more casual on this account afterwards.
