So yeah, in this event. Most Players use Alt Accounts. and not just one but more i guess.
This is kinda unfair for others who only use 1 account. Cause others may use more than 3 or more as alt.
And what I noticed in warp portals,for example, middle is the safe one and other two are to the city, after the 1st set of portals are gone, the new set of portals stays the same as middle safe and two others to city.
So i suggest that change location of the portals every set.
This might not eliminate all alt accounts. cause its kinda easy to use alt accounts in window mode, but since it will take time to tab and may cause lag, this might be a good way to eliminate them.
