Conquest war rewards is too rewarding it injected the game with lots of gold which only end game players are having. It would be really hard for newer player to cope up with them if this continues. Suggest to lower the 2b reward to 500m. This would still be rewarding but have low impact on ingame market.
If your concern is new players what about season servers? Gauranteed pen ? Free pen accessory? All of which are pity systems that reward the newer players whereas veterans had to struggle for their gear.
Kamasylve blessing or value pack? do you realize that's worth more than the conquest reward of 2b?
Kama makes a big difference in the amount of rng drops and value pack reduces the central market tax by a very big margin, both of which can net you either more than 2b or cost savings of more than 2b per week.
