So I was kicked from Halatali today

[SeraviEdalborez]

OP's position is not about laziness but about skill. OP did not feel comfortable DPSing.
OP's complaint was not about the criticism, it was about the "penalty" imposed.
Kicking a person instead of educating that player serves no true value. But, Elitist A**holes are going to be Elitist A**holes.

Having observed your profile on LODESTONE, I will say congratulations, you are an Elite player by what you have accomplished in this game; all classes done, FCoB gear, etc....
Then comparing it to OPs profile, 2 lv50, and only a couple of items above i110.
Your experience level compared to OPs is significantly different. You have accrued significantly more skill through you obvious time and dedication to the game. Your judgement is "Elitist" simply because you are expecting OPs playing skill to rival how you would play in that situation.

Why is my stance invalid just because I'm on top of the game? Why is it not applicable just because others are not where I am? It's the same advice: try. Do something. Fail so that you know how to succeed. This is how DPS maximize DPS, how tanks maximize DPS, and healers maximize DPS + minimize excess healing.

Healers are some of the laziest and lowest performing players in this game at every level of play, including Coil. The fact that most wait for healing to be needed is seriously not a good thing in any case because anything that needs to be healed should be prehealed for the most part. This is something you don't learn sitting on your thumbs. You try this "wait and heal" thing in Coil and you will let people die all day.

This is a Mr Miyagi thing, wax on wax off. If you DPS hard enough and keep people alive, you learned how little you need to heal and the gaps you can fill with damage/something. If you let them die because you got too tunnel visioned, you learned a limit. You can work to that limit or try to optimize so that it doesn't cause another death. You never learn this limit unless you try. You can apply this directly to an endgame encounter by instead using those gaps for MP generation. Then when you're comfortable enough with THAT burden, you can DPS again.

You can replace the word "laziness" with whatever makes you feel better but it is what it is. A lack of skill is perfectly fixable. A lack of effort is generally not.

Q: Why do people not play healers?
A: because of people like SeraviEdalborez
Just kidding

Excellent healers know how to DPS and heal - which is basically what Seravi is talking about.
You'll have to constantly push yourselves to improve if you want to get there.

However, I feel that it is unfair for people to expect all healers to be able to do both?
My stance is that a healers job is to heal. But if you can heal and DPS, that's an added bonus to the group.
Perhaps I have lower expectations of my pug healers?

I have lower expectations of pug healers. Heck pug everything. I do not expect pugs to be playing as hard as possible. I expect about 70-90% success at the mechanics

Improving does tend to take some self pushing sure, but I don't demand that of others in a pug run.

Invalid, no, that is your opinion and you are entitled to it; IMO, it is excessive. Your expectation of player behaviour is slanted toward cream of the crop skill/behaviour. Life as whole is not at the cream of the crop. Expecting every player to play at the cream of the crop level an unreasonable expectation for society.

Let me propose a situations to you:
You are a team leader of 6 people.
Members 1-4 are highly skilled and competent.
Member 5 is moderately skilled and very dedicated.
Member 6 is poorly skilled and unsure of himself.

Are you going to ?
1. Educate and encourage members 5 and 6.
2. Educate and encourage member 6 and fire member 5.
3. Educate and encourage member 5 and fire member 6.
4. Fire members 5 and 6.

A consequence of firing a worker is loss of productivity, and time spent replacing that worker.
Applying this analogy back to the described instance OP talked about, he was member 5 and got fired. Would you also fire member 5? Or would you choose another option?
You might attempt to argue that he was given a chance to improve before he was fired, the stated warning he was given. There definitely was no encouragement though, it was definitely a threat.

The reason you and players that share you opinion will find so much flak is because it the opinion without compassion and patience. Two desirable qualities in a person according to society.
