i never said make it have to be purely based on pinpoint optimal play i'm saying that it needs to be increased so you don't have to rely on others for enjoyment from YOUR OWN JOB. all cause you actually know how to play healer and deal with mistakes. cause at the end of the day you do have outliers that occur but if the consistent requirement is so low that you literally have no reason to not just pop an ogcd on somebody who eats a mechanic thats the issue. you should be forced to think about is it worth me popping the oGCD on them now or save it for x mechanic coming soon. you've never touched savage nearly at all so you have no idea how many people actually expect to carried and how many people leave and one person or two leaving a party isn't nowhere near as bad as a player expecting to be carried, at least if they leave you can remake. not find out two + pulls later they actually don't know alot of the fight. and either carry them, or teach them the fight anyways, or kick them and remake. the fact you lack the knowledge to understand the amount of time lost by both accounts is exactly why you should not be arguing.
also if you actually paid attention to vercure you would know it's basically a cure 1 pre 85 (150 less potency post 85 but still nothing to scoff at) but on RDM which is quite useful on multiple occasions not to mention dual cast allow you to cast 2 vercures in the span of 3seconds. if i see the tanks barely hanging on and both healers are down there's a reason why i can keep the tank up while my healers get up from laying on the ground dead. and yes SMN has no heal (well thats effective) but they do still have swift cast raise which is still far better than nothing and witht eh ruby ruin changes they now only use swift purely for movement or rezzing now anyways
also sounds more like you need to quit strawmanning your arguments and understand that maybe just maybe there's healers that actually you know KNOW HOW TO PLAY THEIR JOB and don't want to be punished cause little timmy here is still spamming cure 1 in 90 content or heaven forbid the party wipes in O12n oh no it's almost as if that's called learning (in some cases relearning)
