I get what you are saying but there are plenty of times when I 'pre-heal' with HoT skills so I can have a safety net for DPSing. Like if you see me apply Medica 2, Regen and Asylum I am about to Holy Spam until Thin Air is done. Is it wasteful? Probably. Do I care? Not really. I like keeping the party topped up so I can have those windows of DPS and people complaining about overheals is not something I want to have to deal with. Especially with healing being the chore that it is now.

I'd prefer overheals to a 'green dps.' Just saying.
