Virgorous Spirit used during FoWSC

Depending on how good your MT is, the entire UA bar is pretty much redundant. there shouldnt be very much cleanup to do anyway, and Seed Of Life if anything is something you should drop. half of the pug UAs ive seen enjoy putting seed on the tank whilst he's balling, which can pull aggro and whipe you. If you're confident in your tank/team, run Mo/P with 11 heal, 11 divine and 8 in command (cons put this up to the 9 breakpoint). Bring Cant Touch This and Fall Back instead of heal party (healing tanks to over half hp is pointless- they function better at half) and Vigorous Spirit (shouldnt be much cleanup) and then if you want to, finish him! or ymlad instead of seed. you shouldnt need to be redbarring. people either need powerheals from patient + dwaynas, or theyre better off dying + being ressed at max with UA - redbarring someone with heal other/gaze is just a waste of energy. Hope this helps Agreed there have been multiple FoW runs that the UA has left and as the Quality of the MT has been good enough the team has still completed the run from Forge onwards without a monk.
HOWEVER this is PUG runs we are talking about the MT is usually a PUG and the standard of them is usually pretty low. So assuming that the MT is going to be bad is generally a good Idea for the monk

As for seed of life the same rule is in effect. I am of course assuming that you are talking about a PUG run. This means that you are going in with people of generally lower exp that a guild team. As the monk you should recognize this.
Seed of life in the wailing forest can be extremely useful especially with the high rate of fails that occur with the canyon pull. (Where the 100bs jump over the canyon to spike the wailing lords[quest] group)

The OP referred to using vigorous spirit. For each attack you gain hp. Or skill used etc. The idea of the spike is that the MT balls the group and the 100bs/VoS jump in and everything should die in 1. Giving them an enchantment (in the 100bs case) is going to make the shadow mesmers in forge reason to change target to use shatter enchantment on them which is going to make them lose more hp than they would gain. This being said in the case of VoS having an well timed cover enchantment could be useful so that VoS isnt stripped.

It all really comes down to what sort of team you are running in. A guild exp team doing t3 way would drop the monk all together. If the spike is clean enough. BUT with Pugs it should be the monks choice as to what build they feel comfortable with.

Infuse health can be very effective as a full health heal, with UA up it (should) fully heal any team member however if this member has agro using infuse will break the agro on to yourself

Air Of Superiority is nice in the same way it is on the spikers and MoP etc. Having the large numbers of mobs that die, you get a good chance to get lots of energy back and a instant recharge on all your skills. This can be particularly useful if things go wrong.

Heal Party- as MR said quite so plainly that healing a tank to above 50hp is useless this isnt always true. Again as I said before it depends on the quality of the tank. If the MT is less exp then having the odd heal when hp is down at 25% can save the day. If the main team is slow on clearing the forge while the MT is tanking the whole 360 agro it could very well be the case that heal party IS needed to prevent a fail. (This being said of course any party wide heal including Seed Of Life in this instance can keep the tank up if its used on the warriors when taking damage)

The main rule of monking is NEVER ever cast on the tank if he has agro) Seed of life may heal everyone to full hp for 5 seconds but after those 5 seconds everyone is going to start dying pretty quick

Run your own build you can heal with. AS long you can heal with it no one should have anything to nag about it. i do think UA shloudt be brought as a fast res. nevertheless monk isnt really necissary in fowsc, can be ran without(just takes a little longer)

i do think UA shloudt be brought as a fast res. nevertheless monk isnt really necissary in fowsc, can be ran without(just takes a little longer) Don't really think bringing UA or not was under debate even from the person you were quoting. Teams expect you to bring UA. Its the best skill to use for a monk in this particular speedclear.

Vigorous Spirit is more for the Spiteful spirit/Empathy spam than anything, it's not required if your MT is any good.

Heal Party is generally useless if the tank is any good; the only other use is if you need to redbar people that are outside your aggro circle. If you have warriors that are attacking themselves to death then we just proved the point that pugs are terrible. Ohwait.
Cure hex or spotless is quite a good one but again as LifeInfusion said it depends on the tank there should be no reason for 100bs/vos to get hexed but on the forge clean (360) this can happen a lot and the bridge pull when the 2 extra shadow beasts pop up. Dwaynas Kiss is fueled by hexes anyway. To put a minor heal on 30 hp per attack compared to the 50+ damage from SS or Empathy seems rediculous.

As for heal party, any tank can be good but there does come a point where 50% block +75%block + the armor can fail you and it's fow pretty much the buggiest elite area in the game. It doesn't hurt to have the back up of a quick 200heal.

Also as for your runes if you take a +3+1 divine headpeice for casting UA you can get slightly stronger heals. (Switching back to the healing headpeice after)
