This is my first time, and i have few suggestions.
Suggestion:
Trade - Souls for hero medals at Mark William
Pros: This will make useless souls that we get in dungeon instance usefull.
Cons: People will waste gold on potions of vitality
Suggestion:
Remove Euclid blueprint from Warlord instance
I belive that most people that get requirements to unlock warlord instance are in that stage of game that they don't need this item. I reaserched everything before i unlocked Warlord instance so for me was and still is usefull as strange fruit

. And worst part is you get them in gold chests (higher score)
Pros: Less useless junk in instances
Cons: Developers could implement some new technology to reaserch so it could be usefull, someday
Suggestion:
Alliance instance map
Similar to Rescue of princase (one map) with required deeds - alliance war medals. In this instance players will get rewards that benefite alliance: silver, gold medals, developents items that we get by braking down gear... and maybe some new items that benefite alliance capital and developement.
Pros: Alliance war medals would be usefull... even if alliance war gets implemented, it would be nice to have options with this item.
Cons: Vitality problem
Suggestion:
Give back option to meet epic heroes in "Hire heroes" list for higher sire level players
This was case during xmas event.... for all, now this time for advanced players
Pros: Geting benefits with higher sire level is good for game and it's fair.
Cons: it could make tolkens irelevant (of epics that apear in hero list)
