Mercy Stroke - Necessary for MNK?

[Allyrion]

You may hate fates but at least marauders are like the best class to do them with (at least for the levels you'll need to get Mercy Stroke).

Mercy Stroke isn't necessary, but I think it's a nice addition to the toolkit. In the long term, the dps it adds is negligible but in the short term it's quite powerful.
Maybe your group is slow killing the first dreadnaught in turn 4, Mercy Stroke might make the difference.

You want extra damage in the last seconds of any of the Coil fights. It's not much overall, but it's an extra attack that's off gcd and the highest potency direct damage attack we have access to.

mercy stroke is pretty usefull when u have to down a conflag asap in t5 ^^.

Necessary no but you dont have many alternatives to increase your dps and mercy stroke, while neglicible for your sustained dps, can help to improve your burst.

I swap between Bloodbath and Skull Sunder depending on what I am doing.

Mercy Stroke is really great to have. Depending on the content your doing and who your going with. Its also really good in T4 on the dreads cause its free DMG and who doesn't like free DMG.
My setup

Mercy Stroke
Invigorate
Blood for Blood
Bloodbath
Fracture

Bloodbath is great. Its true that a mage can heal you, But Being able to heal yourself helps them out a lot. I use it in AK a lot if I take hate of a tank, Really nice in T2 on ADS since you can't dodge vaccum wave.

Incase some people don't know Crit hit effects Second Wind so I can heal myself for some pretty good numbers.

It sounds good on paper but healers don't care, they see you drop by 1000 and toss you a heal so even if you can selfsustain yourself, they don't take risks.
I often heal myself to full with second with after taking damage but still receive heals.

It's "useful" but by no means necessary, it has a 90s cooldown, so you'll most likely use it once or twice per battle depending on the boss, there's nothing else to use in its place so it's kind of a "why not?" situation.

Skull sunder is the highest threat ability I have access to. If I need to tank things I use it (see turn 4, hyrda, garuda).

Why would you need a threat ability? To tank shit when your tank dies? As monk you should be second on the aggro easily without it.
Monks are not off-tanks if we happen to tank something it might work until a certain point but in that case aggro is the least of our worries.
