so...something like a higher authority above leader on rank system. The case of missclick to be selected as a leader is highly unlikely compared to accident kick (In my 8 years experiencing and experimenting creating some clans and story of my friends, never i heard they accidentally put someone to the leader by mistake due to the placement of the leader addition is quite obvious compare to kick). Even when it does actually happen and with the ease of communication with the clan squad through discord that problem could be handle quite easily.
