What about the crit chance of each tick of regen? Since it is 50 potency now for 30 seconds, compared to 100 potency for 15 seconds, we can do the math.

Approximate crit chance at 410~ ish crit rating is 10%

Using that, mathematically we have a bigger chance of getting better overall healing compared to 2.0 medica ii, since it is 10 ticks now, and probability wise we should get at least one crit from those ticks.

Just trying to give a different perspective since everyone seems bummed or finding a reason to be bummed about the Medica II change
