Yeah, it seems if there is a cap then it is high enough you are not going to reach it (in PvE at least).
I'm hitting about 55% buffed. I could push it higher but decided to focus a bit more on crit to increase healing as returns were much better. This seems to have been a good plan given the update 10 changes to the crit system.
I think crit is going to be really important after the update for our best healing. We're seeing the increase from crit magnitude scaling without the decrease from the crit defence changes. combine that with a 45% crit chance -- 25% from rating, 10% from trait, 10% from armour set (assuming the last set bonuses I saw were right), and we should see a nice increase in our output.
