I am playing with one or two friends all the time and we kinda reached a point where we have hard time leveling.
We are around 75 and caught up with lv 85+ quests, so obviously, we can’t get the side quests that have a level requirement, but the big problem is there is no place to bash monsters for us, every map we go, there is only one channel and it is crowded with people everywhere, and most of those maps don’t even have good farm spot like there was in earlier maps.
There is just quests monsters, small corridors and the next map warp, we are spending a considerable amount of time just waiting for 2-3 monsters to respawn here and there and fighting with others to kill them.
