Why we need a 5 person light party
Adding a 5th party slot just for a extra dps member would help.
Main reasons
Long que times for DPS. Adding in another slot allows more dps get groups faster. Que times going for 30mins into 10mins for DPS.
Not enough players want to play tanks and healers. Adding more of these roles just temporary helps que times since the majority of these players just play them to get to just level them to max level.
4 man combat content seems lackluster since mechanics are toned down for 4 players.
Simple to increase all the enemies in all the trash and boss fights in the game. Which is just roughly 15% more health per mob. 5 man groups were a thing back in ARR with a server que in glitching out. However that 5th slot was completely random extra job.
