this retard arena

can you explain why i see 20 ppl on my friend list that are in sarn arena, and then when i ctrl click the arena i always see the same 2 ppl if im lucky (otherwise it's empty) ? i know there are multiple gateways, but since we are 2 ppl doing pvp, if you split us in different gateways then you are really trolling us.
there is something i miss and i'm more retard than ggg or ?

eu/us/aus

and there is no way for me (eu) to join us? because really i always meet the same 2-3 ppl, and most time of the day arena is empty.

change gateway at the login screen

yes but then i've to play with 100+ ping... i mean this thing splits pvp population even more :|
