I did it on my Asura. It is definitely difficult. It reminded me of playing Donkey Kong Country Returns. However, I do not see the problem with the event. It is designed to be difficult. The word “achievement” has connotations that have unfortunately been water down. It is part of an optional event. The Clock Tower does not prevent people from experience any part of the game or the Halloween event except for the Clock Tower.
I understand that not everyone is good at platforming, but every part of the game does not need to be accessible to every type of gamer. I don’t care for the PvP, so I will most likely never get the PvP achievements, or even the monthly achievements since they have PvP components. But this doesn’t bother me, because there are many other areas of the game that are accessible to me and that I enjoy. This type of complaining will only serve to water down the game and make it a generic experience.
