I'm neutral on this topic. I understand it's use, but I also understand why it's an annoyance to many users. I've personally never had a problem with it, even with my horrible Australian wifi, but I've seen that's not the case with others. We have to keep in mind it's roles in FH.
1. Protection from hackings, DDoS and other nasties (whether it is actually a high-quality security measure, I'm unsure, but we haven't had an issue since the hacking, so I think that's saying something). There's still toxicity in the community, there always will be, and if it's taken down and someone gets word, we might have a round 2 on our hands. It's a risk, and at this stage where the game is almost a ghost town, something like that could bring FH to it's knees and with Raz M.I.A, I doubt it'll survive.
2. Ad revenue. FH and it's site can't run on nothing.
I'm not saying I'm for or against the login page, but there's all different pros and cons to the situation I suppose. It would be ideal to return to how it used to be, and I know it's been 5 years since the hacking incident, but the staff can only do so much with what they've been given. There's really not much that can be done with the server master absent.
Also keep in mind (or a news flash if you haven't heard already) that a new FH is being created, and I'm sure the staffers working on that project are looking to bring to it what the community are after in a game like this.
