You lost the battle when you let others stream the event outside your channel.
They opened the streaming because at that point the hype for ECL was dying and even during weekend events viewership averaged around 2k even during weekend streams. After open streaming sundays were averaging around 5k all streamers combined if not higher sometimes.
Escape's main challenge is that they do not have anyone known and good enough to stream regularly barring zeroempires and he is busy with other stuff to stream regularly. Without regular content there is no regular viewer base, no hype generation for a one year long event.
Another thing is that compared to other recent top events KOTD 2, BOA, NAC, Hidden Cup the prize pool for LAN final only was smaller.
