As for different grouping with same server speeds (x4 only with other x4 speed etc) I do not want that nor is that a good path. Players on x1 can only be attacked once per hour, maximum of 5 times per day by same opponent. Yeah, they could get attacked more than usual, by no more than 5 opponents if each of them attacks max number of times (and one of them 4/5), I honestly don't think that's an issue, everyone had so many years to prepare and make good accounts by now, especially those on the top with so little opponents.
Are you sure of what you are saying?
to start, forgive me if my English is not very understandable, but I can organize myself with beautiful drawings made on Paint, in order to make everyone understand
As you can see HERE (yes, I know, I like so much when I do something nice )
There are many aspects involved in different speed server. Start with the easy one, ok?
Server x1 have a normal regeneration ratio of AP/health, have only 5 Attacks against one specified opponent, can make attacks every hour, can use potions only every hour.
Server x2 have a double regeneration ratio of AP/health, have 10 Attacks against one specified opponent, can make attacks every half hour, can use potions every half hour (so, every 30 min I have to remember to log in to put a potion, while the server x1 is ok for 1 hour).
Server x4 have a x4 regeneration ratio of AP/health, have 20 Attacks against one specified opponent, can make attacks every 15 minutes, can use potions every 15 minutes (so, every 15 min I have to come inside the game, 4 times in one hour to be pair with a server speed x1).
Server x6 have a x6 regeneration ratio of AP/health, have 30 Attacks against one specified opponent, can make attacks every 10 minutes, can use potions every 10 minutes (so, every 10 min I have to come inside the game, 6 times in one hour to be pair with a server speed x1)-
Now, talk about serious things... the orbs
Using a bit of simple math, I can obtain the formula to calculate the cost of a 100% chance orb (eeeeeeeeh using hellstone is too easy and not anyone can use them for orbs)
So... the formula is (LVL * 7200) * Speed of the server.
Think we have an account level 1357.
Speedx1= (1357 * 7200) * 1= 9.770.400
Speedx2= (1357 * 7200) * 2= 19.540.800
Speedx4= (1357 * 7200) * 4= 39.081.600
Speedx6= (1357 * 7200) * 6= 58.622.400
This only about the cost... what about the duration?
on the Server x1, you can even create orbs for 4 days.
on the server x2 the maximum I saw was 2 days
on the server x4 the maximum I saw was 1 day and 18 hours
on the server x6 I don't know... but I think the maximum can be 1 day...
So, in conclusion, even only for the orb is something we can't handle for many time, is something that have to be resolved. Because one server x6 speed to be pair with a server x1 needs x20 or x30 fragments more.I hope my little, little experience, can help.
And what exactly is the issue here? Regarding orb costs, are you not aware you also get x4 gold from missions? It's extremely easy to save up to billions of gold during less than 20 days, even more with events!! I myself have had 14 billion gold on my account around the level you specified there, making orbs is the least of anyones problems. Literally 2 missions of 50-100m gold will take care of the orbs for the day.
Also, no, you don't, as you can only attack those players 5 times, not 20, not whatever speed is in question, FIVE, which the duration of the orbs covers.
