usefulness of healingblast/healing sphere

Was I the only one that found these medic artifacts relatively useless. When I am playing my medic, I do a pretty good job at keeping the peoples health around me pretty high. Since the healing sphere doesn't heal for very much, I mostly used the it to figure out if anyone else needed any healing, but I could just buy medic awareness for that. For the healing blast, the only time that would really be useful, is for when there is a large group of people that need healing. That doesn't happen very often. Usually there's just 3 or 4 people that need healing, so it's just as fast to use my healing rocket and save the adren for other artifacts that I can make better use of.

So, I think that making the healing blast larger, but heal for less would be best. It's not very often people need more than 200+ health and people aren't usually grouped up extremly tight. As for the healing sphere, I would make the rate of adren consumption for leaving the artifact on slower, make the rate at which a player is healed faster, but also make that healing drain adren.

It would also be nice to either "throw away"/trash the artifacts if you don't want them or make another level of loaded medic to receive the artifacts incase somebody doesn't want them

edit: guess I'm alone on this, so nevermind
