First I would like to congratulate you on your first step to learning how to reason by being able to think this subject from another bodypart(Ankle ?? rly bro?? holy shit). Your setences does not make any sense, plz try harder. Making healers oom would indeed be a great idea, just like I previously mentioned(why so mad lol) however this does not take anything away from the fact that heals are way to strong to begin with. Games today rarely end up with a 3-0 win, even before the wsg timer nerf to 20 mins.
The healing state right now forces games between two decent teams to pretty much be whoever scores first wins, and I dont think this is great for the bracket as it promotes having a D consisting of around 4-5 heals and some cc dpses while they kite and wait for stacks to reach a decent ammount and then have 3 stealthies hopefully blow up the other teams fc. Thanks to this mop has in a lot of ways gotten even more class determined, seeing as burstin the efc factor heavily outweights other options such as hunters, mages, dps shamans, dps palas, warriors , who can still do great/decent in mid but just lacks that initial open burst that rogues/druids can provide.
Because healing is so strong, it is literaly impossible to stop people from going thru mid if they have any sort of heals thus making the classes more suited for open battle less important and mandatory. If heals was not as good as they currently are we could see a change in the meta game for good and hpalas/rdruids/rshaman would not just be able to run in 300% speed over mid if they were being attacked as hots and instants would heal for less, forcing them to stop and actualy cast something.
You might think that instants are fun and balanced as a rdruid. I however would like healers to have to cast , thus giving a chance for people to actualy interupt(which has a nerfed cd of 15 secs now so not like it would destroy healers lol, just demand some fakecasts).
TLDR: Stop talking about peoples ankles, they are personal. Major flame intended xo xo
