Partial Easy Solution Remove all outside clan chatting ( In game that is) Devs can make it so that you can only PM / Wall those inside your clan. Now that doesn't change the fact of alts or outside game chatter. But its a start Basically same thing as they did with only being able to hire allies within the war your in ( No outside Hires) If those go to extremes outside of that to cheat in wars and the get pinched then they should just be banned from game ( themselves and who they were in contact with) Honestly why do you need cheat to win ? is it because you, yourself just plain suck at KAW ? or just a coward? Wars are bad enough with all the loopholes and exploits as it is. Last thing we need is just lazy ass cheaters. Oh and on a completely different note.. if you don't have the mith/gold for the 4 spell and no xtal .. DONT SIGN UP FOR WAR!!!! you want EE and Mith earn it like everyone else by doing your part.
It's really not the fact of inactives, the main problem is alts, and moles, which I don't see walling will help with, I know a certain player, that when I was in the small bracket, was casting 2-4 alts per war. And had 1-3 on each team.
Xtals aren't required Good war clans have them as a requirement, but not everyone will xtal in an indi
tbh as far as cstals a whole team xstaling unless they are top notch ee fighters can be really bad. a select team of xstals though can be efficient. on the mole thing it is near impossible. i suggest start building a team of people you know war well and want to win mith spells boost stats but items is more pertinent
