You know how sizeable percentage of global discussion is about the personal challenges between players. Of course, some of them are childish like, "my base is stronger than yours", "i can 3 star your base", "you cannot get even 1 star against my base", "i have more skills than you because of my war stars", and so on.
But believe it or not, that is an important part of what the game is about. So here is a feature that takes that thought further:
Personal Global Challenge:
in short: it is a way for two players to challenge each other and get a mini war between them similar to clan wars but only for few minutes, without any disruptions to their bases, with great emphasis on global chatting.
a) One player challenges another player in global. He sends an invitation to PGC (personal global challenge).
b) second players accepts the challenge.
c) this takes them to a different environment, similar to clan war environment where not of their bases, current troops, shield, loot, storages are affected. it is a separate environment that does not disrupt at all what they have now.
d) each player goes through the following orderly process:
1) first pick one of the war bases.
2) pick which troops, from your own troops level and availability only, to fill out your "war cc"
3) finishing this point allows the second peron to attack if he is ready.
4) pick a virtual army limited by what troops are unlocked and what level they are. Also limited by army base capacity
5) pick a spells likewise. All of this does not consume any elexir, or resources, nor takes from any existing troops you have.
6) fill your virtual CC with troops from what is unlocked by their level.
7) you have about 5 minutes to attack. or something reasonable. 3.5 minutes for raid. and 1.5 minutes to select all of these. or a little more. remember, that is a personal global challenge and players in global are waiting for the result
8) the victor is determined by number stars and number of percentage destruction as in clan wars.
9) the victor does not get anything at all whatsoever. except bragging rights.
10) the result is posted in both his personal profile and is seen publicly and possibly in the global he is in
11) each player gets 1 free PGC per day. if anyone wants more, the cost of each one is 10 gems
12) Players have the option to turn off PGC so they will not get invitations.
imagine the excitment about this and the practice opportunity it will provide. Of course, this is from high level point of view and many details are needed. Global will not be same after this.
