I think it would be great to reset all trophies to 0 (infact the entire leaderboard to 0) and start afresh. You would keep your Dread Level intact as to still get the bonuses since you did legitimately get there. By doing so it would give a fair chance to all new players to try and get to the top. Some people these days have like 40,000 + trophies and there is NO way you will ever get close to that given the latest version of DK.
The game has changed SOO much since it originally came out in terms of trophy points. For eg. You could earn trophies at a MUCH quicker rate in the early days, I saw a guy earn like 45 trophy points after ONE raid. The cap currently is set at +15 trophies for attack or defense that you can win in one go.
Yes I do realize I will get some backlash from current leaderboard players and rightly so as they did earn it... however to make it fair to all players.....
Also, it would be nice if the devs could make it possible to view what trophy points came from attack and defense. That way we can see if players are strong in attack or in defense
