hi teddy
for the fist part i do know exactly why it was implemented like it is now

- this is not the point.
the point is the second part. and sure they do not want to cheat. but as a solution for those who would like to play with 2 accounts on 1 computer, it could be - if some of them are catched as cheater - to accept the ban for those 2 accounts. so i mean it could be like the commitment you do when you install the aa25assist, you have to say - yes, i am agree when 1 account would be catched - dosnt' matter the reason - you can bann both accounts related to this computer. so easy and more players and more fun with that - and no bigger risk at it is already now.
my friends would accept this rule (and they wouldn't if a hacking mind would lead them).
btw: you are right, this case with 1 player 1 computer was many many many many times discussed. but maybe with a new idea it could change, right? the world is still rotating ...
