1) "x4 with vitality it does not mean x25 interlude" 
I said it's like x25 Interlude, and it's not only about rates, it's about NPC buffs till 75, common equip, Pailakas/Kamalokas, insane XP reward quests, much easier leveling curve etc. x4 HF is about as quick as x25 Interlude. 
  
2) "Where did they write "we are classic.club"? 
They didn't, however if it indeed is a project by different people, the resemblance is uncanny, even if it's just on the 'inspiration' part. 
  
3) "I am sick of both srvs you mentioned because they are just russian servers that care just for money, no support and everything is based ONLY on DONATE."  
  
Then there's probably one thing you should keep an eye on: 
 
 
  
THIS is the reason they decide for the faster x4 rates. 
  
They copy the donation system from Classic Club - the ingame store for items is pretty much nonexistent, but they earn most money on manually adding items to items auction.  
  
x4 rates = people reach the consumption level quickly = the items auction is more profitable. x2 rates = people get stuck on low levels where they can just use common items. x4 rates = they reach 76+ and 80+ quite quickly and they'll consider buying the ++S weapons because they're going to keep them anyway. It's a common sense really. 
  
If they cared about players, if they wanted to make a longterm server, they would go for x1 or x2, but they didn't, so it's obvious they just want money. 
  
They can keep saying they want to make a 'longterm and stable' server but those are just empty words when they make these midrate settings.
