Hi there!
Since the bonus from items for a single skill is capped at 50%, a needed balance update was made.
Now all Legendary items can give a bonus from 20% to 25% (was 25-30%). This means that it's possible to have all 6 Legendaries which give +50% for 3 skills without any bonuses lost.
Additionally, all Rare items give a bonus from 10% to 15% now (was 5-10%).
Epics remain unchanged: a bonus from 15% to 20%.
This update also means that all Rare items crafted before this update are giving +10% bonus and all Legendaries are giving the max possible: +25%.
