What you are saying is actually result of how well coded is pairing program. Then, always how a player is using his/her team, human creativity. If I had been paired against top leveled summoners, I would have never reached Champion 3 league. I am doing it because my opponents are allowing me.
Saying that all problems regarding lower valued decks playing in higher valued leagues is solved by Collection Power is wrong because there is a way of getting specialists of game making to improve in-game systems. Side affects of Collection Power could be more negative to Splinterlands game.
I am finding pairing systems (ranking, tournaments) and system of random number generator being poorly implemented by Splinterlands developing team.
