(1) Sometimes, the Defence Configurations are not properly updated to reflect the current configurations.
I have been noticing that my attackers are not fighting against my current defence configuration. Many times my attackers were fighting against my old defence configurations set up hours or days ago instead of the current one. This is very frustrating.
(2) PvP battle matching is bias and is not consistent.
(a) In the first battle of the current PvP season, I was matched to a player with 17 trophies less than me. I won the battle but only get 26 trophies.
(b) I was attacked by a player who has 51 trophies more than me. When he won the battle, he got 43 trophies.
17 trophies advantage, scoring 26 trophies <-- Me
51 trophies advantage, scoring 43 trophies <-- My attacker
(c) After the first battle, I am matched up with players who have 140 or more trophies than me and their defence monsters are 10 levels higher than my attack monsters. It is extremely difficult or nearly impossible for me to win any attack.
Conclusion: This PvP battle is getting ridiculously frustrating to play. If there is no improvement in the near future, this PvP thing should be removed.
