Ah the age old "Why is the Artist not working on programing a new client?" First there are is nothing saying they are not working the issue. As pointed out to some of us on another board there are not just 3 people working this. There are people from all facets from the old game working, They have just revealed the 3 best know names.
Second where have they been up front and honest with anything they have told us what they are trying to do.
Third I have only ever seen them saying they will look into it and do their best, I have yet to see time lines for anything, but when grandfathering is ending.
Forth they have already said they will be giving email codes once they feel they have advanced the game to a stage that would interest old subscribers. Do you not think it would be the same for Unity players once they figure out what they are going to do? Maybe they see a way to create a third shard but have to get the US sub base built up first to afford the serves. But I guess you do not want to wait for that chance do you?
Fifth I have yet to see them not trying to go out of their way to help people and not screw them over.
Personal I am sorry that another company screwed you over and that you have to wait for the new company get on it's feet and tackle one problem at a time, but honestly they do not have to do anything, But I do not see them as the kind of people that would stand by and not do anything. So maybe look at all the good they have done, no comparison to the last company, and calm down and give them some room and time.
