I have looked up 'the tree incident'. Medica2 vs Rapture has nothing to do with it, the range on Rapture and Medica2 is 20y for each. The bigger issue is 'the player didn't do their job of healing, because they were busy making a tree', and that's got nothing to do with 'are HOTs good/not good'. The player who Arthars pointed out, who he was expecting a heal from, was within healing range of Arthars with both Medica2 and Rapture, from the moment Arthars stood in position to make his wind-bird-thing merge to the moment he died. Even as they were messing around making a tree, they were well within the 20y range
But hey, since you say 'the only place Medica2 is an option is High Concept cos it's downtime', here's
a clear VOD of a group, week 1, using Medica 2 for Natural Alignment 1.
And
here's another. And
here's another, this time from the POV of the WHM.
And you know what, just for good measure, here's
Arthars' own clear VOD, where his WHM also uses Medica 2 for Natural Alignment.
