Taunt and healing.Follow

I am not a MT , but a low lvl monk (23), so I sometimes get to be 2ndary tank when its necessary to pull off the healers or if MT leaves group I tank for a few pulls till we get a real one. What I have found is that its hard to keep all aggro on yourself when pulling group mobs unless you are also throwing in some AE attacks/ taunts as well. Doing this of course creates the risk of adds. I usually pull with Range item OR using distance attack (really depends on what the nearby environment looks like ie. lots of mobs in close proximity or open space. Then if the area is open the first thing I do once I have pulled mobs back to the camp is throw AE taunt on and continually hit my target with Taunting Slap, re AE taunt , rinse and repeat till all mobs are dead. That seems to be most effective to keep mobs off healers. When there are lots of mobs close by things are a little different, since I dont want to keep getting adds. In this case I useually just ask that the healer be sort of close by so that I can switch targets and /taunt as needed if mobs attack healer . This way I am not draggin mobs all over trying to find the healer , resulting in loosing aggro off other mobs and getting adds. /ramble off

ps Dont you still just hate how some idiots pull aggro off the tank and when you tell them DONT GET AGGRO, they respond by saying they cant help it : (

as a 19 war i use anger and rallying cry and i never lose agro in groups of mobs or singles

I thought I'd add that group HO's are more effective than solo HO's so while starting of the fight with your solo HO would be effective for getting more hate, It's faster to kill enemys while utilizing the group.

So far I have only been able to purposefully generate a group HO with my brawler and my wifes mage. I start she smacks it with a bolt, I taunt she smacks with another bolt. Another one I have done was with a scout and a fighter which is along the same lines the fighter starts and the scout triggers. Yesterday while grouping with my new quild we triggered a huge HO that boosted our stats immensly, but it was accidental and I didn't keep track of what was done. Needless to say the final wheel after it was trigger required a spell from a fighter type, a mage type, and a scout type. The buff only lasted for 30 seconds but it saved our buts as we were all down to our final bit of power and very low in life.

I had a paladin die cause he cast DOF on me he died fast :P I pulle dhte mobs off him but the dot killed him

As a guardian I sometimes have a problem keeping aggro on the second target in a group of targets. Usually it is when a high damage mellee type is using auto-assist (ie he has me targetted).
The trouble is that after the first is dead and the second hits me the mellee type is smacking away already while I'm still waiting for taunt to complete, or even in the time it takes me to see that I have a new target and to hit the attack button. This also can be a real pain when you have an enchanter class locking things down because as soon as I target the mob in order to drop a couple taunts on it and make sure I get more hate than the chanter then the mellee type has a target from me and probably didn't cancel his attack button and so he wakes it and it turns on the skinny chanter. Not good. No matter how much I say to people not to use this helpful feature of the game I guess the temptation to target me, hit follow, then hit attack, then go and make dinner/drinks/whoopee is to great (I admit I love doing this when Im not main tank).
So, to help with all these scenarious I learnt to use group buffs as aoe taunts, which is what they are - as stated earlier by Mokuba. For a Guardian Battle Tactics seems to be the best one but basically now I almost never cast these buffs when NOT fighting - they are too useful. You other warriors just use whatever group buffs you get.
The other thing worth mentioning is that if you do lose aggro on a mob you can use protection spells on the player getting hit and you can target them through the mob thats hitting them. Target the mob and you can taunt and attack it while at the same time drop protection (Allay, Stand Firm, Sentinel etc) on the poor skinny that the mob is beating on without having to retarget on the player. Plus the mobs hate this tactic and turn back to you all the more quickly, with a group buff thrown in I can get the aggro back of a player pretty quick no matter how many buttons they are mashing.
