The next update should be -
lvl 8 -
Archers -should upgrade to a better and stronger bow such as a miniature Cross bow 😱
crossbow + terrible AI = mini Archer Queen 
Barbs - should go ham, with two swords... So on
Lvl 6-
hog riders - the hogs them selves should revive armour and live a little longer 😑😑
i agree
lvl 6-
Healer - in general needs an upgrade 😵:
what would you wanna fix with it ?? 
and I also think that might it be a good idea if when you go to train your troops, when the barracks tab comes up with the little pictures of each troops, the picture should be what level your troop is, say if ... The level 7 archer picture should have purple hair and a tiara ( if you know what I mean ) another ex is my drag picture shouldn't look purple should look like red with fire coming out of its nostrils ( as in the level it is ) hope this all make sense, sorry for the inconvenience but just throwing some ideas out there. And I'm new by the way lol
