I didn't get the hate for this event then and I don't get it now especially for who have already got everything from it.
Personally I don't really like the garo event because I'm not fond of pvp, but I'm honestly not complaining about them adding it. besides it runs for a couple of months meaning that getting all the weapons IF you really fancy that mount or you are a completionist is not something very hard to do if you manage your time correctly.
