Lord of the Rings Online extensively, odds are good that you're familiar with the concept of stat caps. Functionally, stat caps are that certain point at which further increases to the stat in question will be wasted -- useful for balance purposes, but rather frustrating when players find new abilities and equipment useless due to the stat caps. So it's probably going to be a good thing when Rise of Isengard makes stat caps largely a thing of the past.
That's not the only useful takeaway from the new developer diary, however, as the game's statistics are also undergoing further revision to make the game easier to understand at a glance. A new stat, Finesse, will be added to specifically reduce your target's ability to evade or resist attacks. Resistance, Mitigation, and Critical Hit will all be merged from their current state (so melee, ranged, and tactical critical hit will all become simply Critical Hit). Finally, there are some changes incoming in terms of interactions with primary stats. It's a short diary, to be sure, but the implications for Lord of the Rings Online players should be far-reaching.
