I do it to body block Assassins and take Blitz hooks. Plus they give armor to nearby allies in case the assassins still somehow get to the carries but my friend says I should put them in the front to bodyblock more damage and make better use of their abilities (Braum’s Shield). Who is more right in this case?
Because you don't know who you will be facing you want to put them into frontlane. I mean there is no universal solution. If you put them into front, assassins will murder your carries and you lose. But if you put them into backline and you won't play vs assassins but normal comp enemy frontline get to your carries and you lose again. So perhaps the placement might depend on the probability of fighing assassin squad, ie. how many players are in game and how many of them has a assassin team comp. But there is not much time to scout enemies and make the math so I just use normal placement (and then get wiped by assassins).
Only when you will know who you are fighting (ie. just 2 players remained) then move it accordingly.
i think you have the right idea, if you put your Guardian in the back and you have at least 1 other tank for the front then you should be good, even if it's like darius/garen/mord or worse case scenario WW.
Guardian makes more sense in the back imo
