Rory Newbrough (A.K.A Drybear) has just released a dev insight video talking about season one and some upcoming changes to Paladins. The video can be watched here:
One of the most interesting changes to us here is the, quote:
Easier to understand build system
The implications of which are not fully known but we’ll keep on the lookout for that.
Another change on the way is a talent system which appears to allow you to augment parts of your champion to improve them, these may either work with the new build system in leaving the stat upgrading to this separate system, but that is pure speculation on our part.
But as always, nice skins are on the way to reflect what mastery you are at.
