Thoughts : ridiculous.
In my patch 5 playthrough a lot of ennemies use it to cure their ally. The result was that the healing surface often healed more than one ennemy.
This whole mechanic is a shame and it looks completely silly. Once again, the game wants to be serious and mature but it has ridiculous gameplay element because "it's fun".
But it's not fun at all... It's just another thing that break the immersion for the sake of it and that does not add anything interresting in the gameplay.
Being able to give a potion to someone would be cool. Throw it in someone's head or walking on a surface to heal is stupid.
+ 1 I completely agree. I can’t give someone medicine by smashing the bottle over their head. The entire concept is stupid. Not to mention you can use a greater healing potion to mass heal your entire party. It is game breaking and makes healing spells pointless. You can do an entire play through without a healer at all just by having a ranged character lob bottles everywhere.
