Pvp has devolved into a race for the T0 gear. It should be more challenging to face opponents.
The game economy is horrible. Gold, food, and runes need a sink. The shard tiers are still bad because the superior shards still drop at a much higher rate.
Kingdoms need a much needed buff. The kingdom bazaar is always out of stock. Buying marks with food is currently heavily rationed on a trust system for this reason. Get rid of the limits on buying goods or at least expand the bazaar. Give the kingdom more goals they can accomplish together.
What is the end game? Dungeons just lost the ability to farm marks. The chests you get with them are brimming with trash for you to salvage at a pittance. End game needs a better reward system.
Actual gameplay is still pretty static. The new mana system does encourage player to utilize more types of spells but there is no purpose of healing in the game because of how much damage is being done relative to a players life bar. Why heal or generate armor when gaining barrier from a Dwarven necklace is so much better? Enemies should have better board changing abilities and harsher debuffs. Comboing should be encouraged more so the gameplay is less mindless.
My 2 cents
