In the greater available experience:

with an open enchantment board, is it better to cast a gem producer as early as possible (use almost all your gems) hoping that it will take long enough to dispel that you make your investment back. Or save up to 100+ and try to make it difficult to dispel?

Later castings you'll start playing with trying to make it stay up, but for the first is the risk worth the possible return?

And on the other side, once an enchant goes up - should it be first priority to figure a way to knock it down? Just so the benefit doesn't snowball for the caster into beefed up future castings? In a larger game, do you find that people will generally let an enchant stay up because:
They don't want to be the ones to waste the gems dispelling
they want to save their gems for other things
they may not have the paths to dispel/recast

There was a game a bit ago where Jot put up Astral Corruption... and it seemed the rest of the board couldn't group to dispel it, does this happen often?

I guess it comes down to, is it best to just take what early slots you can afford and hope for the best? Or save up for a hopefully difficult to dispel cast.

Especially in larger games
