Something has to be done with the Grenadier fragmentation upgrade: VII supply with new grenades (fragmentation grenades efficiency +1500) This is ridiculous, there is no point even making walls or any other structure for that matter, only 5 Grenadiers can destroy a fully upgraded tower (the 1 blacksmith and 2 academy upgrades) in literally 5 seconds its gone, an entire section of wall can be destroyed in seconds, even cannons, howitzers and mortars cannot do such damage despite the fact they were historically way more powerful and the fact that Grenadiers rarely if at all used their crude grenades to destroy buildings. Every game its the same strategy, players just build Grenadiers, do the upgrade, attack your wall and within seconds they are in your base, I've even had enemies destroy an entire wall section so that the map is open, by the time any of your units can reach them it's too late they are in your base. It makes having walls obsolete, seriously what's the point? It needs to be reduced massively, you can have the fragmentation grenades efficiency upgrade, but reduce it massively to 50% or 100% and reduce the throwing time of the grenades. It's by far the stupidest thing in the game.
