Char power has been tied to economy since the dawn of the game.
Pots flasks enchants vantus runs health pots armor kits the list goes on. Hell crafted gear exactly what legos are have been there since the start and at points being bis for set slots for quite a way into given xpacs. Even crafted legos are not a new thing.
Char power being tied to economy not only should happen it has been a core part of the game for a long time. If you don’t make gold to pay for all the power you can get you are quite a bit worse than those that do. Always have been always will be.
You can make more gold an hour now than garrisons ever did, speaking from experience of playing now and durring the garrison day. That is hardly a excuse to not have money.
