As far as Chain Heal target selection, I really don't get the argument. CH takes 1.8-2.2 (depending on haste level) seconds to cast. That's more than enough time to decide where to cast your next one. How does that "require reaction time"? The real thing that takes away some of the decision making on casting CH is that it's rarely worth casting it on a target that doesn't have Riptide on it (and you are limited to 3 of those without RT glyphed), but that is frankly more of a problem with the Riptide-CH interaction than it's a problem with CH not having jumps degradation.
