I agree with you. The categories were not a terrible idea, and stopped the last minute training and sh boosting, but the attempt to fix the initial problem has meant that when a clan wins a category, they basically stop fighting, or farming on tile without DGs.
Clans with lots of smaller players are at a disadvantage especially when running the siege tower. So, my suggestion is to get rid of the total number killed, and add running tasks to a new category (tasks only seem to score in KvKr nowadays).
I quite like the current set up - our single oponent had more influence than our entire clan and at lv40 was several palace levels higher than our biggest players, but it was a close contest all the same - until he made the mistake of farming without domain shields at the end because of his much stronger troops. A "failed" attack on one of his tiles was enough to win us that crucial 4th category. (I.e our attacking troops didn't knock his troops off the tile but they did not need to in order to win the attack category).
