So currently we have Raids focusing on Kingdoms and Invasions focusing on troop types. Both ideas are inherently good.
The issue is, that some troops will focus on things like devour, or poison, or status effects. All of these are used a lot in normal game play. That is what some troops are entirely focused on and thats it. Without those that troop is useless.
Now the issue comes down to the Boss in Raids is immune to all of this. If you have a kingdom that has a few troops that focus on these, they are useless in that team, and therefore wont be used, limiting your troop pool even more. Invasions is even worse. None of the troops in that team can be hit with any of it. EG this week, Wulfgarok is the current Mythic for Wargare, and you cant use him, because his entire purpose is to attack, and then devour. But since they cant be devoured, you cant use the strongest member of that troop type.
What I suggest, is removing the block everything on every single 1 of them, and have 1s that have different weakness’s that way the full range of troops can be used in each of the different events, rather than further limiting the limited pool we already have.
