GW2 needs to adopt WoW's LFG system and here is why.
I would’ve agreed with the opposition if I continued to do AC runs. But I stopped doing AC runs because I got everything I want in AC and it is boring.
Now, I can’t get a group that isn’t doing AC.
4x Necromancer, 3x Mesmer, 4x Guardian, 4x Thief, 4 Revenant
It contributed greatly to even further anonymity in WoW, that led directly to people more and more often acting like twats, as there were no consequences of their actions. When you assemble a group manually, and you get whispered by a player that has quit your previous group mid boss after having a fit, you simply do not invite him. LFG forces whomever upon you.
If you have no time, or can’t be bothered, to waste 5 minutes trying to gather a group together, chances are, you don’t really have time to complete an instance either.
It’s not hard, as you said there is no trinity, it takes literally few minutes at most, you get to at least say hello to people as you invite them, something rather rare in LFG and practically non existent in LFR anymore. The only exchange between pugs in WoW nowadays are insults or loot disputes. So no, there are games out there that offer the tools you are after. Let this game stay clean, as it is. Encouraging people to play together, have fun together, and not just mindlessly press buttons completely disregarding that the other 4 in the group are humans not NPCs.
