I just completed my 4 piece T10 (2*264 2*251) and have to say i'm completely distraut over the magnitude of the 4 piece bonus. On training dummy, it accounts for
only 1% ONE PERCENT of total damage. This is after giving up the 2p T9 with critting moonfire which gave about 3-4% extra damage overall. T10 4p
Lasherweave Regalia - Item Set - World of Warcraft puts a 4 sec dot on the target for every crit, which is almost always refreshed ... seems to be refreshed with lesser wrath crits over starfire ones (50% lesss damage). You'd think it was a 7% damage increase, but if it's constantly refreshed (let's say every 2 sec for starfire or 1 sec for wrath. it's really only max 1.75-3% (rough estimate). Add to that the refreshing with lesser wrath crits over starfire and it's even less.
breakdown from training dummy:
Starfire 620.6K (42.8%) (72% of them crit)
Wrath 583.5K (40.2%) (45.3% of them crit)
IS 123.8K (8.5%)
MF 105.6K (7.5)
Languish 14.9K (1.0%) (only 51 ticks!)
14.9 K / 51 = 292 damage per tick on average
(that's 292/12400= 2.3% of one average SF or 292/7800=3.7% of one average wrath)
that's totally broken! at best it should stack cumulatively on the target or put a seperate languish on target for every crit landed. as is, it's useless.
this is from depleting entire mana pool on heroic target (without innervate). Looking at my spec, i see that i cna go from 1/5 Genesis to 5/5 Genesis to maximise the effect, but it's totally not worth it to get +4% on 1% damage.
what to do!? going to do this again and upload to worldoflogs or something ot show you.
