I am gonna say that you haven't played in this server as long as you should have been.
1. No class right now can achieve 0 after cast delay. All skills have their delays buffed up, arrow vulcan cannot be spammed more than 3x at a fast rate. You sacrifice a lot by using 3 kiels.
2. Legendary Items are ,honestly, too easy to get nowadays. We even had a vote forsaken king set. There is absolutely no reason for you not to get decently geared in a matter of days. So I doubt there are people that do not have at least legendary + Knight set. With that said, I don't see anyone being a punching bag.
3. Any Physical hitting class that gets EDP will be OP. A sniper hits 40k FAS without thanatos, add EDP to that formula and we got OP. Champs hit 90k+ each asura against people that has dual raydrics + gr, adding EDP to that seems absurd. Oh, and no decent champ would actually suicide against a paladin. Would have used TSS then.
On the Legacy MVPs. I do not see this,in any way, helping new guys. It would just make the strong and rich become stronger. New guys would not be able to camp LHZ MVPs as there are many Veterans camping the place because of a particular quest item.
It's a nice suggestion, do not get me wrong, but it would need tons of toning down if we would implement this, and I do not agree on most of it. I would have preferred creating new custom MVPs so that everyone has an even playing ground. Because if we implement this exactly as you had said it, I would have made 1 SinX Alpha card right off the bat on my legit, and I am not even that rich compared to others.
