With xfaction in place the travel time for people and the waiting time get out of control. On top of that we have new zones which made the world even bigger and harder to traverse.
And i have to mention it here ongoing ddos literally killed the motivation to do dungeons for a lot of people. To much time invested high risk u wont even finish it and extreme long waiting times for party members.
I think its fair if 3 people get to the dungeon to summon the last 2. Probably from another faction sitting on the other side of the world.
This also is a huge problem for the LFT. When i queue wide spread to get the best chances on a dungeon run i cant prepare the journey. If i sit in Grim Reaches and WHC pops well thats 30 minutes of travel time. If u have a tool thats lets u queue multiple dungeon then u should have a tool that makes reaching them possible.
If u want to back it with some RP then make a questline at lvl 15 or sth. where u gather mats and build a summon stone. That could be a little gold sind a bag space filler and a little downside to the added functionality.
Just my thoughts on this.. But u can leave it and see people skipping the added content and or boosting themselfes in a antisocial playstyle. I would prefer hanging around in dungeons more with people and having fun instead of waiting walking or not doing the run at all.
im playing Warlock btw.
