Why does ZOS care if we can see minute changes in meaninglessly large numbers? It isn't going to make those double-ended health bars budge any more visibly.
I'm not sure how the new consoles work. Are we sure they can't use addons?
The only reason they inflated the numbers is so that when you increase your 100 stamina regen by 0.4% it doesn't still appear as 100 in the character menu. They never showed damage numbers before so not sure how that relates to the issue. Relatively its generally the same (except health only has a 10% factor on other stats instead of the previous 50%).
Seeing the damage numbers should be implemented for console users if addons won't work.
