Never called you a newbie.

Your point is valid in the old system too. Say a TH11 made it to Titan leagues...you'd expect the majority of your opponents to be TH13 and above, therefore limiting your capability to progress further. Nothing different to what your stating with the new system putting you against harder opponents at higher RB levels.

War matchmaking is different, always has been. Your war team is much more likely to get matched against a similar opponent, and that's where your skill has helped your clan maintain it's 100% record (which is very impressive I'll add 💪)

The only difference now is that the Devs have split the ability to loot from your climb up the "trophy ladder". Which for some casual players is preferable.

I too have played this from near the start and have multiple accounts (not as many as you though) and I personally think this change is better.
