I don’t like to use its power anyway.. I much prefer to post convincing arguments that may influence others in the use of theirs

DT was not supposed to be a power seeking position and considering it as your own property. Unfortunately some power seeking users are using it as a tool for them to silent others. They are using the loophole of the voting system. Even a post against their argument will earn you a tilde.
but it's probably better to suggest how to improve it directly. Less DT1-members isn't going to change much, and requiring more inclusions for DT2 hasn't been implemented for years.
(1) Requiring more inclusions for DT2 should be a good start.
(2)
It requires more brainstorming. i.e. To be DT1 you must be in other DT1's (99) trust list either as added or as tilded (avoid not having them at all in your trust list). I can not think of how because every time Theymos run the corn job it add and remove new members but as I said with proper brainstorming it can be done.
