Temporal Chains map modifier in 0.2.1

The patch changed the Temporal Chains modifier to a randomly targeted curse. It is definitely a lot more bearable, but often I still find it is just not worth it to play it because:

(1) It is a -40% magnitude; AND
(2) It lasts 20 seconds.

I find myself waiting out the debuff when I get caught in it. And it makes me want to avoid bigger packs and draw them out bit by bit.

Sure, GGG may think this is exactly the kind of gameplay to enforce, but really all I'm going to do is to go back to throwing away temporal chain waystones.

If it only lasted 6 second I'd probably be fine with it.

There's really no reason for it to last 20 seconds. When temporal chains would kill you, it takes all of 3 seconds to kill you. When it wouldn't kill you, 20 seconds of it is still not going to kill you.

Another way to design this is to have it put a stacking debuff on you. Each stack adds 10% magnitude and lasts 1 minute. This makes players avoid the curse while also make the occasional mistake bearable, and makes it so that the risk of carrying on playing with the debuff is acceptable for the occasional mistake but fatal for repeated stacks.
