War Related: Spectators/New people should be unable to see traps/teslas
This suggestion mainly comes from the idea of spies sent to other clans. There are so many threads created reporting other clans for attacking knowing where the traps are that I think something should be done against this.
My suggestion relates to the Spectator rank (if you can call it like that) from the Wars. The spectator rank or title appears when a player is not participating in his own clan's war but is only looking. This can either happen if the player is new to the clan or if the player has opted out of war.
The idea #1: The spectators from the war should be UNABLE to see the traps/teslas of their own clan mates.
Reason: To stop the spying in other clans.
Advantages: People will be unable to spy in other clans and as a result less fake reports will be made on the opposing clans.
Disadvantages: Their own clan mates which are not new to the clan will be unable to see the traps/teslas of their clan mates BUT they can ask one who is participating to show them.
The idea #2: The players marked under the title New should be UNABLE to see the traps/teslas of their own clan mates.
Reason: The same, to stop the spying in other clans.
Advantages: People will be unable to spy in other clans and as a result less fake reports will be made on the opposing clans.
Disadvantages: Very few! Usually the players that are new but didn't join the clan to spy DON'T need to check their clan mates bases.
Why I think this idea can be implemented quite easily: Because the spectators are already prohibited from donating troops to the clan war map, so if SuperCell could implement this prohibition I think they can also include one for traps/teslas.
Preventing spies to join the clan during war
Either one will work. but it's better to NOT accept these spies in the first place. I suggest to provide the last clan the player was a member of. this can be included in the player profile. this way we can just reject the request to join if we see the last clan was the current enemy clan. it would also be nice to have the last 3 clans the player was a member of so that we'll know if the player is a hopper or not.
