The events are perfectly fine per se, but I feel the pricing and exchange rates on these events still alienate people that can only afford to spend a limited amount of money in the game, which seems to be a good portion of the player base, if not the majority.
Not to mention that, at least for Europe, 1000 euros is not the same for someone that lives in the UK as for someone that lives in country where 1000 euros is significantly more than the average wage. That's a whole other issue though.
