With So many changes, i don’t see why we won’t get a rank reset.
Look at all the c2 and c3 skills that are moved down a rank.
For example, double chance is moved from rank 2 to rank 1. That’s enough to make someone want to consider kabba1 in a build when they wouldn’t before.
Or the fact that wugu has gu pot (an aoe) in circle 1 and not circle 2. What if current wugu2 only wants wugu1 due to gu pot and ‘enchant poison’? Along with the other skills that have changed ranks, think of the new builds you can have now.
Besides, what would a single rank reset (2 if you have archer and cleric on your account) actually hurt?
EDIT:
I will also add that ranger2, which was never used in a build cause it sucked, actually has some use now due to steady aim changes and new steady aim c2 attribute along with time bomb arrow -maybe- being useful now.
