So what do people think about marks doing something more than pillars? Personally I'm in favor of it, nothing OP of course, just something more interesting than a pillar, but I know several people who are against it. So I decided to make a post here and see what the rest thinks.
My suggestion: Stacks with your mark if it has the same element, otherwise it acts like a pillar that last for 3 turns but produces double quanta.
This is only a suggestion, what I really want to know is what you people think about marks having different effects than pillars.
