Placeable Hex Totems
Let's say that as a killer you decide to pick ruin as a hex perk. You start the match, but instead of it getting destroyed after 30 seconds give or take, you start with 5 dull totems as always and you can choose which dull totem you can use as your hex totem. You would go up to the dull totem and do a short interaction. Of course your perk wouldn't be active until you do this. I believe this would help killers, and make it so that their hex totems are always in good spots.

Part of Hexes is the gamble. Being able to choose which totem went where would mean that people could just pick the one that's easiest for them to defend, versus the game's current implementation which gives big risk/reward and encourages surveillance rather than camping.
Picking a good spot for your hex would exactly be the point. And If a killer choses to camp his totem then he would be sacrificing time protecting generators. Its really no different than choosing to face camp a hooked survivor.
Your 'exactly the point' is just bad game balance, and the entire point of hex perks being high risk, high reward means it's hopefully never going to be considered.
