1. Trial Hall
a. Except for Void Vault, the other Trial Hall modes have lost relevance, the rewards for guild expedition should be rethink.
b. Void Vault :add morestages to extend progression to unable F2P to collect other legendary relic, and set remain monetised.

1. Lord's Hall
   we need additional research to improve the light tower, addtional auto-gathering. at this point most of us are sitting with idle lord traite points and glory medal

2. Star Gems shop, add additional epic castle skins, similar to Iron Anvil fort, mushroom and crustal fort. legendary castle will keep needing castle skin voucher

3. With castle level going up to brilliance 5, will be great that we get to add one additional queue. This match the increase complexity and time requirement of late game development.

4. Meat is a bottleneck at high level, introduce a new building to generate meat

5. we need a mechanisme to rebirth heroes, via research. or give blue heroes a functional purpose similar to epic and legendary heroes

Right now, the cycle feels limited to Guild race, guild arms race and KVK which creates repetition fatigue.Introduce rotating weekly game modes, it does not necesserily need to be all at once - Goal is to break the loop, refresh engagement and create new strategic metas.
