I'm really sorry to hear you're having these troubles. However, as upsetting as this is banning players isn't the solution I would agree with.
TBH they deserve to have their darn IP's banned and their computers confiscated for being such selfish children, but ostracizing your paying customers is really bad for business.
They need to add another tanking class. This attitude is due to the rarity of the position needed for a party, so take away that exclusivity.
I mean, I'm not saying it isn't wrong or that it doesn't suck. I'm simply stating the reality of the situation. If you want to change it, start rolling healers and tanks. If enough people fill the roles, they won't be rare anymore.
Nothing I said isn't true.
Interesting that a couple people actually condone the Lancer acting that way. I wanted to point out that as a "DPS" I was not given the chance to even play. The Lancer simply refused to tank because he wanted all the plate.
Making more tanks would definitely improve the quality of LFD but than Lancers would get butt hurt that they can't DPS and their ques aren't instant anymore.
I'm dreading this when my Zerker gets to 60. I usually queue with at least one other person, but I haven't made friends with too many tanks yet, so I have a feeling I'll run into this problem eventually. ;_;
