Hrmm.... spell casting subtlety 3 makes this a little hard to test. But after your post I had to try it it just to verify. In either case we had a bard pull for minimum pull agro.
Test 1. Nuke on incoming so that nuke lands when mob is about 16 HIE steps away from tank and the chain nuke 4 nukes after tank engages for 4 seconds.
Warrior = Able to get mob agro off of me instantly on INC never failed. While continuing to chain nuke I would get agro, but after popping a disc warrior agro was restablished to warrior.
I died 4 times on this method after 30 pulls.
Pally = Able to get agro off me 63% of the time (19 pulls out of 30). Continuing the 4 chain nuke after tank engages, the pally was not able to restablish agro too often without me dying. I died a total of 23 times. Might have been all 30, but then I had a chanter replace the rogue to cast runes on me while pally restablished agro. That method kept me alive for the last 7 'tests'.
In either case I did not run away from the mob, I stayed put close to the tank do that their DPS can restablish agro. As myself and the group witnessed warrior agro > pally by a long shot. The DPS was not questioned.... warrior again > pally.
Test 2 conducted today.
I would not nuke on INC, instead I would let the tank engage the mob for 12 seconds before I do my nuking. The nuking was consisted of 5 chain nukes.
Warrior was able to sustain agro on the first 4 nukes, never failed. The 5th nuke was split right down the middle. 15 times he could hold agro, 15 others he could not. In either case I did not die, by the time the 5th nuke got off the mob would die or was trying to run away from low health.
Pally was a coin toss on the 4th nuke, 50% right doen the middle again. 5th nuke pally was unable to reestablish agro no matter what. From a pallies lack of DPS, I died 12 times doing this as I still had mad agro and the mob was mostly not low enough on health to run away.
Testing still shows warrior DPS is undisputed between the two. Warrior was undisputed king. As for agro... again they are better. Both in obtaining it, and definately has a edge on holding it. All this testing was done at the projection of body (weaponry trial guy) in MPG where all mobs are lvl 70.
Now given I do not do that in groups all the time. I just had to test pally agro holding as you think it is better. Maybe if the pally were GoD geared instead of PoP geared... it might have been tied. Warrior was using that trash living blade spear from DoN merchants while the pally was using Vazazir something dispair from Time. Both were equally hasted. Warrior had the belt from the war in GFay while Pally had the MPG trial one... so one being more hasted than the other is no a condideration. There might have been other factors as to why. But it has always been my observation that warriors get/hold agro better than pallies. Pallies are undoubably good at it, but they must bow to the superior capabilities on this matter to a warrior.
As for DPS... even in the AA's maxxed for offensive, it is said in there that a warrior will be better at it.
Keep in mind, I do like pallies in my group, when they do their job in order as said in my first post for this. Or when a warrior in the group simply is not available then they can tank. XP will come slower with a pally as main tank, but it still will come, you cant argue with that
Now that I lost a boatload of XP running these two test for something experienced players already know... now it is back to the game to regain that which I have lost in more conventional methods... well now that I got a better idea on when and when I can not nuke in MPG on pulling... the XP should come by faster with more DPS
