Well as much as i LOVE this feature/bug i must also admint that this might ba a turn off for beginners and its somewhat strange. I can live with it on or off but this change does also require a change of tactics. Now (with it off) the better strategic place id on top of a map as its harder to get hit. With damage through floor on the position directly under the victim is better. Both require a certain skill!
A argument against DTF would be that with 'off' both people have at least a chance to see and hit each other. If one does look down to hit the opponent he becomes visible and hittable.. So its more fair.
And some maps (blood prison, toxic, darkplace) demonstrate the power 'off' gives to mappers. Just create small gaps, cracks or holes here and there were one can do prediction shots or lob a grenade into.
Oh and the electro combo has a huge radius so this feature might be overused with it and spoil the balanced gameplay.
Never the less i voted yes to reenable it because i really like the twist of shooting below someones feet
