I honestly didn't even think people like this existed. 6 HP per second is never, ever going to save you. That is entirely your monk's job, whereas you're wasting attribute points, a skill slot, and setting yourself up for shatter. Same with healing breeze, that skill should never be on a warrior's skillbar. There is no situation where you are going to be taking damage to the point that your monk can't keep you up, but where an additional 6 HP/s is going to tip the scale. Please, if you actually run mending, uninstall guild wars.

You are right. Running Droks or Desert Runs, monks can keep up with warriors and cast healing spells on them on the go.

The reason for Mending isn't supposed to be the absolute best saviour in the game. If it were, it would be an elite, better, and not free in pre-seering.
Poor played WAMMOs think Mending WILL save them, but it just delays the inevitable.

Please tell me what enchantment heals constantly and cannot get shattered? I would like to know, because if there is no such spell or skill, then please do not mention Mending gets shattered. Weapon Spells are not enchantments, so they do not count. The can heal for a brief time and cannot be removed, but again, cannot save you indefinitely.
Most monks do not have the ability to manage energy (I've been in groups where the monk recklessly spams healing spells until I read "I have 3/45 energy").
I don't care if a Warrior casts Healing Breeze or Mending on themselves, but yes, wasted attribute points (should be in tactics where Healing Signet is used). As long as the warrior doesn't recklessly aggro needlessly, I'm fine if the warrior has mending on.
I do run mending on my Ranger when he runs, and I USED TO run mending when I had my young monk (she's now experinced and has not used mending for a very long time). Please note, monks don't always heal everyone at the same time, monks do not always have quick reflexes when a warrior needs healing (I've died because a monk said, "sorry, lag"). Sometimes a small delay (caused by mending) may delay death long enough for you to get the real healing you need. Not all warrior skills use energy, so why not use what energy you do have?
I don't hate mending, I just do not enjoy watching people put on mending and then aggro everything they see.
