WRONG. Oh how ignorant and weak people can be...
The question is who's being arrogant, though. See, for me the kitins are merely a minor annoyance. I'll hit speed+mpa to run past them, and do my digging. There are some safe/semi-safe places left, so that's no issue. If I do get aggro while digging, I can still run, and even in case they kill me, so what. Digging yields no xp anyway, and DP is gone in 10 mins. Lastly, if Loria really gets too annoying, I'll just dig in Wastelands.
Now it looks a LOT different if you only have speed-2 and mpa-2 (or maybe not even those) and 1200-1500 HP, and if you're trying to get your non-master dig skill up. Maybe you don't have 60 fame to buy PR teleports either. Now in that case, you're screwed, as you will die every time and you'll spend your day digging off DP which is neither fun nor immersive, no matter how often you are told "you know, life on Atys is tough". The net result for you is that you're getting nowhere while the veteran players have all the fun.
Dying for doing something stupid is something most people will live with and accept. Dying (several times) because you're being "punished" even though you didn't do anything wrong is something that doesn't go down nearly as good. Not getting anywhere is a killer.
Groups of 2 or 3 lvl 75 or higher can take out some kitin in the lvl 100 areas.
They might, if they are lucky, but they'll work off DP most of the time anyway. On top of that, these players are being punished by excessively hard mobs that give very little xp compared to what they could be hunting otherwise. Don't tell me there's no difference in killing a furious KotD (60-80% melee resistance, many HP, hard hitting, social) compared to a parched stinga or a gruff bodoc, all of which will be 3000 xp to those level 75s, but the KotD being by far the most painful, and the only ones not dropping anything you can use to get your level 75 craft up.
Is the amount of xp important? Well, maybe not to you and me, but it may look much different for someone who sees that everyone except themselves is 250, and they just can't get forward.
Treks are still being held, or at least being attempted.
Hahaha yes

I've wiped with a group of 4 (two multi-250 and two ~210s) trying to trek the latter across the Fount (Fount-BB-ToT). Thanks to the excessive aggressiveness of KotD, their huge numbers, and the broken taunt, it is not hard at all to pull 3 groups in one go. Now, this works ok the first time while auras are lasting, but the seond time, the outlook is grim. In the end, we did this trek with the help of another two people (250), which worked ok... but seriously, this is just ridiculous for a trek that you could previously run solo if your tourist was able to give you a few heals every now and then. How is a group of level 150s supposed to do this? Basically, "exploring" is non-existent for them, and getting to any other area is reduced to "find a big group of 250s, follow close, don't look left or right, and hope for the best". Trekking used to be one of the most fun activities in game, once upon a time. I used to drop anything to get on a trek. Now, they're annoying, not fun. Trekking now means having to cut a trench through aggro for every 10 meters you walk, rather than sneaking around, enjoying the landscape, and with some luck hitting a few nameds on the way.
The exact same complaints came up the first time they flipped the switch for the KoTD event.
Confucius said "Study the past if you would define the future.".

But seriously, I hope that it ends before all the newbies are gone forever. See, if you make events that have such a gross impact on everyone and that cater only the 25 most hardcore cracks in the community, then in the end, those 25 people may be what you'll have left as subscribers. It's not like Ryzom hasn't gone bankrupt before, and I would hate to see it happen a third time.
