The main problem is that these events become harvested so that it will be unplayable, it makes little problem now is that even on powerful computers it is totally unplayable fps instead of 50 that are 10, which is like tetris. The best solution would be to make it back as it was and to maintain or drop, but the ark of the events put on the account.
Then, even after the patch is AC (Ascalon Catacombs) nearly unplayable because the lizards spawn at higher fps drop from 50 to 10!!
