They used to have key card battles. Those got removed then replaced by the hiests. Things can be removed from the game. Here are ways to make it better:
1. Ship arena and regular arena attempts are combined. You only get 5 attempts between the 2 of them. Pick which area you want to do the best in.
2. GW has oppents capped at gear level 11, level 85. That is the highest difficulty. After level 85 GW should become a solo TB. It's your own TB and you go as far as you can. Advancing phases at your own pace.
3. Overhaul the raids. Combine rancor and haat into one raid.
4. TB reduced from six rounds to 3 rounds for the battles.
5. Allow sim of previous completed events.
