3500 Gold and a Portrait is so uninspiring… Every time I see this reward it feels like you basically get nothing for completing this stage. It needs to be spiced up a bit.
How about at least adding 5 arcane single color traitstones that match the current tower’s doom color? People need those to power up the doom troops anyway, so it would be a fitting reward. Throw in the 5 gems that most of the previous stages have and stage 7 won’t feel like such a waste, and will stop being a progress killer for lower level guilds.
