Rammus jg item

Rammus is the tankiest champion in the game. He used to be a jg. Now he's a top. I still need to try that. I tried to see if it could but got jg and I said fuck it and picked him. I tried the runic echos sunfire cape build and also a rylais. The rest was armor. I went 6/12/21. I really fed my team but also fed the enemy team but. More so my team and we won. I'm curious vif I should've gone full tank instead of slightly ap off tank (not to be confused with full ap rammus). Same for malphite jg. Kind of want to try it but I still know he's almost as good as a top as naut.
