It has always seemed irrational to me in the practice of government to allow tricks and gimmicks to influence legislating. Even when a filibuster required actual effort, the subject matter should have been limited to the bill under consideration, with limits on repetition. You know, like real debate...

This modern thing of defaulting to needing 60 votes not only changes the mechanics of approval, it also often avoids potentially useful substantive debate.

My vote is to keep the filibuster, but require it to conform to serious discussion of the issues. Make 'em behave like responsible adults!

You never change things by fighting the existing reality.
To change something, build a new model that makes the old model obsolete.
