I don't know, if on average it is around, say, 30 hp after 1.5 sec you only take that extra damage. What I mean is that it changes the may the shield is used: if used to go in and absorb bursts there is only a little difference in effectiveness and a higher skill requirement to time it right. If, on the other hand, you used it to disengage after cooldown had wased out, it makes you much more vulnerable to ranged or DoT retaliation.

It absorbs the same in a high-damage situation, but much less on a low but countinuous damage situation..

This means that your options for shield usage are even more restricted. You don't loose tankyness for going all-in, but you loose tnakyness during harassment situations, engage-disengage situations and so on.

I don't think you will have additional trouble vs Rene or olaf, due to their damage being quite bursty, but I see a lot of extra trouble vs the others you mentioned.

Anyway, I agree that a double nerf is always too much (see last taric nerf, for ex), creating a severe risk of overnerfing.
