All SAAB and SAM players please place only 1 unit as defence and give low-age players a chance to win the Hard opponent.
1 real unit is OK.
1 Rogue is too fake.
I said this because I encountered a player who placed 1 rogue as defence and I find it very interesting.
What a good angel that guy is, to spread the joy!
Now when I think about it, I have a good idea for a different kind of PvP based upon that encounter.
The idea is a little complicated and need to be broken down to the following steps:
1) A dedicated army of 1-8 units should be selected as the attacking army and cannot be changed afterwards;
2) That army when fighting in the PvP tower and win, gain experience, and at some point (experience threshold), level up;
3) The dedicated attacking army when leveled up have higher attack and defence becomes different from the ordinary army, it becomes the "hero army";
4) It might be wise to select only 1 unit as your attacking army because the experience from winning is attributed to that unit in a concentrated manner so that the unit levels up faster;
5) Now the lower-age hero army when leveled up high enough, will have a chance to win against defence army of way-higher ages;
6) The defence army will still be ordinary armies, because if the hero army is used as defence, we would be back into the loop where lower-age army has no chance against way-higher age armies.
We can call this RPG based PvP. It will be much more interesting. Players should hurry up and train their "hero army" or "hero unit" in the PvP tower. You may spend diamonds to train some super-heroes even, which will make the developers happy (and rich), too!
