Im not going to go technical, cause frankly.. I don't know how
I solo'ed skyfire writs last night, and just walked around beating the crap out of everything i saw. I had points in trample, the agi line 40% auto attack ae. I usually run around with out divine aura, but decided to try that and heal crits last night.
The first run, I did it with aoe trample, and completely obliterated the entire JW mobs 2-3 sometimes 4 at a time, wiht just my usual set up, full str, 4,4,8 agi,sta, 4,4,5 int. NO divine aura and no crit heals.
Just ran straight to my mob, pulling anything that got in the way, if it leashed, fine, if not, just fight it. I did just fine, averaging 2.5-3.5 k (epic weapon, full tso tier 2 legendary, all 6 pieces).
Now, i went back and respecced, and took divine aura and 5 heal crit points, so no agi, meaning no trample.
Still obliterated the entire zone but in a different way...my dps was way lower, but my health was amazing, i would be at 50%, without divine aura, hit quick heal and group heal (shadow points in group heal) and was at 95% everytime, it got to be a pattern, when i hit 55% i would hit those two heals, and leave my sacrament of bayle and holy touch for emergencies... It got to the point where i would grab 4-5 at a time just to use divine aura, making me wish i had my trample back to make the fight go quicker. My dps was lowered, but my survivability rocked. As you would expect.
So when you say, keep divine aura, or put points in heal, or you should do trample for aoe... its tough. voes/coa, maidens, you want trample, all TSO zones you want trample for trash mobs, and divine aura for named, so its tough

I personally am playing without Divine Aura in favor of the agi line because we have outstanding healers.
THANK YOU FOR POSTING THIS, cause in a main tank role guys, your aa set up with heal crit is a definite plus in raid zones, most are single target anyway, and its really nice. We did Nexona last night, didn't kill it, but the set up was perfect.
Very much appreciated.
Question, spell crit.. what is the difference between 70% and 54%. I know its 16% but you have to choose between 8 points in trample and 8 points in spell crit. I took trample and my dps is nice. But I do not know how to compare the extra percentage of spell crit/vs ae auto attack damage. Can anyone help on that?
