other games do throttle everyone to the same speed which i dont think this is doing tbh since lag only happens when u are with someone with potato internet. However, i think the best solution would be to enhance some skills activation processes like how when ao is using a skill he cant be stopped with other interrupts. Like they c*low for if u use an interrupt skill it stops all skill ability for that round (creating a new status).
This might be more or less due to the global scope of the player base where connections are not as equal as other instances of this game. So it comes with the territory of operating with open access.
