Try doing Pug HM titan with your relic+1 as whm. So dumb. You can barely cast anything and still be 2nd on hate list for 50% of the fight.
Whm threat seems to be tied to their weapon level? Or perhaps healing per cast? Like a whm who heals 750 per medica would pull more threat in 1 cast then a whm who heals 500 per medica but does it twice.
The problem with whm threat is it sullies their niche of being a burst aoe healer. Because we have to hold back on aoe healing for 50% of the fight.
Yes Twintania does kind of make you feel your whm tools are inferior to the SCH. >_>
