Which will not be many people. At least, not those who have heavy armor as an option (ie: Clerics). Armor now matters...a lot...and heavy armor is WAAAAAAY better than medium for those who can wear it.Also for those who use mithral full plate (eg cavalry plate)
Plus, garbage lootgen items from level 21+ quests are better than 90% of all current epic items. You can get -in any level appropriate chest- a +8 wisdom item. Not raid loot, not collect-challenge-ingredients-for-2-months, no need to spend 7 million platinum maxing out your cannith crafting...just pop a few chests.
Kobold sentient jewel still hate you.
There urgently needs to be a re-itemisation as a result of these changes to put divine caster bonuses on melee weapons/ shields and/ or general clothing/ jewelry slots. This needs to be throughout heroic levels and not just new epic gear. A cleric should be able to both swing a sword and cast effectively. Caster orientated clerics also need to be able to do decent damage, obviously not as much as an arcane but reasonably competitive amounts at least; otherwise outside of raids there will be a decline in the most sort after grouping class. Not a good thing for grouping as a whole.
