I claim that i know what I do because you started to say that it's lazyness while... it's not.
I've been patient to explain why and how healing and dpsing works and you're saying this.

What do you want me to say now?
Seems like I can't argue because for you, a dpsing healer is someone that doesn't know his job or is lazy.
That's what I feel like.

I'm healing on this game since a long of time, I've done ton of content (dungeons, extreme, savage). I'm not claiming "i'm pro-player", but "I know my class after all this time and thing always are fine when I heal, even if I dps".

I don't know what is your main classes, but if you aren't a healer, how can you tell that i'm doing my job badly then ? =/
