I'm proposing that ET should require relations as in the case of sabotage wizards. First reason is that with the war proposal system, one kd can get the jump and ET the other side before declare effectively neutralizing their opponents tms. Obviously some will hate this because it's a part of their strategy. Unless I'm mistaken, it's rarely, if ever, used outside of hostilities or war anyway so it should only affect war proposals by forcing this damaging op to wait til declare after which all's fair. The second reason is more nefarious, one kd gets a friendly kd to ET their opponent before they accept a war proposal giving them an advantage while their opponent regroups and is unable to op.
