Actually yes its their fault.
When they are designing encounters they should set a level a latency where the game is still playable. If you take the Wow team, they are designing encounters to be playable up to 500 ms latency and heroic encounters are still challenging ( and playable for me).
All the ISP in my country won't get me better than 300 ms, so i guess with their design philosophy in mind, it means i can't play this game ?
