About to use my level 20 5 person party into their first instance

And i need some tips on healing. What macros are you using and such ( is there a mod to make this easier)

I use
/target focus
/Cast Healing spell

i have searched for this on the forums but could not find anything on healing.

There's absolutely tons of stuff available here, but it's a bit hard to find.

If you post your group composition, perhaps people will be able to offer you some specific suggestions.

Tank Pally
DPS1 Mage
DPS2 Ele Shammy
DPS3 Boomkin
Healer Priest

questing is no big deal cause you kill stuff usually before it reaches you. I have it said so when i push #2 i cast FB LB Wrath and priest heals tank. Not effcient at all but when someone pulls or is hit with AOE i find it really difficult to heal so i was hoping there is a simpler way to do it.

I also use priests for healing both my 5 man teams.
Before getting my X-keys i used the Num Pad with specific macros for each char for healing with modifiers. 1 key for renew, flash heal and bubble depending on what modifier used. (1 button per toon) 1 key for AOE healing as well.

Worked like a charm for me.

The thing i do with healing is keybinding macro's to specific roles.

i use a G15 keyboard wich gives me extra butons on the left side of the board. To those buttons i assing Alt+1 Alt+2 etc. same with Shift and Control

Depending on how many keys you have. If you have the newer one, you have 6 buttons ( alternate with m1 m2 m3 for a total of 18 buttons ) assing the first 2 ( G6 / G5 ) to the pally , the others with renew ( or another fast heal ) and apply'd to the other roles. This eases the targeting up a bit.

So you have some quick respons buttons purely for healing. You could also do this with the numpad, but i like the G15 keyboard for this.

If you have an older G15 you have like 54 keys or so , think that one will do for all you party members. The new G19 has 36 buttons i think, but stil prices at 160 euro's atm.

Start simple. Make a macro you can spam the snot out of and not use up all your mana right away. ( I use a /castrandom macro with several ,,,,, to allow me to spam it). Then have another key that you can use for emergency tank healing (i.e. it only heals the tank using your big heal). Then make a macro that throws out a small heal (Flash Heal and or Renew) for each party member, including yourself, and put them somewhere convienent. The number pad was convienent for me, but I also have a g-15 keyboard so I use the left side now. Once you level up it a bit it gets more complex, but easier, for a priest at least. You will have several AoE and incidental healing options.

I don't like to change targets, I just cast on who I need to. So for healing, I use:
/cast [target=focus-target, help] HealSpell
/cast [target=focus-target-target] HealSpell
The first one is so I can pick who to heal or heal someone outside my party (BG, etc). The next one is heal whoever has aggro. I like that since even if a pet, a alt, a anything pulls aggro, I can heal them.

Just my thoughts on your team. I am defensive player, so I might not burst people down, but I try to almost never die. I would put down a healing stream totem. It is easy, simple and auto-magic. You can get it at 20 through shammy quest. Yeah, it takes forever to get, but worth it. I would use holy nova for AOE healing. You can get a glyph that makes it stronger for heals. I can't really suggest judgement of light, since you have all casters and wisdom will help more. But later when you get seal of light, I would use that since it should mean less heals needed for the tank. I also love food. Cheap, easy, don't need reagants anymore and gives stam/spi. The stam means that the alts have free health so you should have to heal them less (in theory). Also, it is messy, but holy light has a glyph that heals 5 people for 20%. Sure the tank shouldn't heal, but for super lower areas <40, it probably won't be too bad since can only delay casting 2 times (2 hits) and it is just until you get chain heal (I think 40 or so). Hope that helps and good luck.
