I'm of two minds regarding anchoring a debuff to a corpse. On the first, I very clearly see why Homecoming made the change, as it does resolve the issue mentioned above. On the other, I myself (and I'd wager many others) tend to treat toggles as "OK! It's on! Now I don't have to think about it" and don't consider having to manage/recast them when a corpse vanishes into the aether; I'd much rather just slap it onto a team mate and effectively increase the blue cost of the move by making it have 100% uptime.
By and large in my opinion it just seems like a more functionally preferable approach.
