Which i'm sure will happen, but I could see that creating a reverse issue where EoTM becomes more valuable than the main maps so I would hope Anet would never agree to that.
I like the thought of this.
And because of the way instancing works with EoTM it may need to be more reliant on match score to determine winners but either way. Ultimately, better rewards to encourage activity in EoTM. They could include greater WvW XP gain too but with more reaching 10k and a lack of reward beyond a singular title, there would need to be a better and more expansive WvW level reward system which is an entirely separate issue.
Yeah, I'm sure they had a reason but I'm not sure that removing it really brought any merit.
As an additional side thought, the bloodlust bonus from ruins could include a better reward for holding them such as increased reward track exp, which could then encourage more unique open field fights.
