You can talk until you are blue in the face, this will not change.
My main is a healer I love getting in groups when dps uses the right kill order, it is a pleasure to heal and I will pass on all gear when they are doing that. When I get in a group where I have to kill the weaks and strongs since they are too important to belittle themselves in attacking such a inferior target, I greed everything.
When I dps HMFPs, I use the kill order. I cannot count the number of times I have been whispered to by healers thanking me for that and them also saying how great my dps is. Either they are lying or donít dps themselves, because I play as a Infiltration spec shadow, my dps is terrible, but more than enough to kill weaks in 1 hit and strongs in 3 or less hits So it looks good if people donít know what will happen if the fight goes over 5 mins.
