Macros I found useful

[Mithrael]

These are the macros i used in beta, thought they may be useful to someone out there. These are based on MNK/DRK, so if you are MNK/WAR just replce "Last Resort" with "Berserk". I'm doing these off the top of my head, sorry if the /equip syntax is wrong.

Boost - When in battle or in between battles just run this non-stop.
[CODE]
/ja Boost <me>
/wait 14
/ja Boost <me>
/wait 14
/echo Run Boost Again!
[/CODE]


Buffs - Run once every 5 minutes to keep your evasion and accuracy buffs up.
[CODE]
/ja Boost <me>
/wait 2
/ja Dodge <me>
/wait 2
/ja Focus <me>
[/CODE]

Start - Boost your attack up to start a chain
[CODE]
/p Starting a Renkei with <insert someone's name here>! Don't butt in.
/ja "Last Resort" <me>
/wait 2
/ja "Boost" <me>
/wait 2
/ws "Raging Fists" <t>
[/CODE]

Finish - Use this just as you your renkei partner readies their weapon skill
[CODE]
/ja Boost <me>
/wait 2
/ws "Raging Fists" <t>
[/CODE]

Stun - Change to a 2-hd weapon to stun the enemy before it uses its special attack
[CODE]
/equip main "Mercenary's Pole"
/ja "Weapon Bash" <t>
/wait 2
/equip main "Beat Cesti"
[/CODE]

Incoming - Use this as someone pulls in a mob. Target yourself first (the first line)!!! I do this because I get bored easily and will jump around "checking" all of the monsters nearby. If you happened to hit this macro while there was no claimed target (or it was out of range) it would just skip the /ta <bt> and attack whatever you had targeted. That could obviously be disastrous. Adding the target to your self nullifies the rest of the macro, because you cannot Chi Blast or attack yourself.
[CODE]
/ta <me>
/ta <bt>
/ja "Chi Blast" <t>
/wait 2
/attack on
[/CODE]

Quickpull - For those times were you are in competition with other groups to snag a monster first
[CODE]
/ja "Chi Blast" <t>
/attack on
/lockon
[/CODE]

Pull - When you are pulling for your group under normal leveling conditions
[CODE]
/attack on
/lockon
/wait 3
/ja "Chi Blast" <t>
[/CODE]

Whois - When you are wondering who is sending you all the incoherent tells
[CODE]
/sea all name <r>
[/CODE]

2hr - Beat the tar out of it.
[CODE]
/equip main "Impact Knuckles"
/ja "Hundred Fists" <me>
/wait 20
/wait 20
/wait 20
/ws "Raging Fists" <t>
[/CODE]

Healup - Increase your VIT for better healing, then switch back.
[CODE]
/equip r.hand "Amber Ring"
/equip l.hand "Amber Ring"
/ja Chakra <me>
/wait 2
/equip r.hand "Amethyst Ring"
/equip l.hand "Bomb Ring"
[/CODE]

I think there is a monster only version, but I can't think of it off the top of my head atm...

ooo - if there is, i'd love to know what it is. These are all of the substitutes i know:

[CODE]
<me> inserts your character's name
<pet> inserts the name of your pet (Delphyne, Carbuncle, Tiny Mandragora)
<t> inserts the name of your current target
<p1..6> inserts the name of members of your party
<scan> inserts the name of the target you are currently tracking via Wide Scan
<r> inserts the name of the person who last sent you a /tell
<bt> selects the nearest target currently claimed by your party
<st> provides a cursor to select any selectable target, cursor starts on your character
<stnpc> provides a cursor to select any NPC target
<stpc> provides a cursor to select any PC target, including yourself
<lastst> provides a cursor to select any selectable target, cursor starts on your last selected target

<tp> inserts your current technical point percentage in the format 'TP%'
<mp> inserts your current mana points in the format 'MP remaining/Total MP'
<mpp> inserts your current percentage of mana points remaining in the format 'MP%'
<hp> inserts your current hit points in the format 'HP remaining/Total HP'
<hpp> inserts your current percentage of hit points remaining in the format 'HP%'
<pos> inserts your current coordinates on the map in the format '(x-y)' - in areas where there is no map (Airship, Ship to Mhaura, Ship to Selbina) your coordinates are displayed as '(?-?)'
<job> inserts your current job configuration in the format '[MAIN JOB ABBREVIATION][level]/[SUPPORT JOB ABBREVIATION][level]'

<scall[0..3]> sounds a whistle for all members of your party
<ncall[0..3]> sounds a whistle and shakes the controller of all near members of your party
<call[0..3]> sounds a whistle and shakes the controller of all members of your party
[/CODE]

<bt> is the closest thing i know of, but obviously, if you or another party member already have the target claimed, it won't help much.
