I just want to adress that i find Grand arena tiebreakers extremly stupid and unfair, the systeam handle the win to the person who has more resource than the competing other player who can still pull a tie.

The Tiebreaker system is arbitrary. Given that it's almost impossible to know whether or not you were above or below your opponent at player lock, tiebreakers seem almost like a flip of the coin.
Regardless, any method they use will upset whoever loses:
High GP wins - "I tied with fewer resources, I should win!"
Low GP wins - "We tied, but I have spent more time/money in-game, I should win"
Random flip - <either previous answer>
Alphabetical by player name - "No fair, giving AAAAAAA an advantage"
In the end, if you set defenses and attack your opponent, ties should be extremely rare events, so I wouldn't stress too much about it.
If you'd like to provide feedback to the development team about how tiebreakers were implemented, the Feedback Forum is the appropriate place:
