"Whoever forgets his history is condemned to repeat it"
Anyone thinking a 2012 permanent classic server will be a big success are forgetting about 2 big factors:
1. The publisher GameForge and pc dev team from BlueHole Studios.
2. TERA back in 2012 was "so great, so popular" that it needed to change from pay to play model to a free to play model. Why? Because it was a massive failure world wide. Players leaving the game in the first 3 months left and right. Korean servers needed to make this transition before the first year, EU and NA was even worse, they need to make this transition after 4 months.
These are not the only reason why the game was a big failure, they only accelerated the process and hey, they are still here doing the same with current TERA.
Another thing to think about is, other games with Classic server works for these reasons:
1. They have a big player base, dozens or hundreds of times bigger than TERA even before they opened their classic servers.
2. Their popularity around the patches they made the classic servers were good if not great. This allowed to bring enought people to sustain their classic servers.
What era on TERA could be considered the best patch to make this "classic server" a better choice and probably a better bussiness than the big failure that was TERA back on 2012? Obviously TERA from 2015. Tadeshi's idea of a classic server for TERA.
All people claiming a TERA Classic server based on 2012 patches will be an huge success, you have no proof, you have no facts, and history taught us well. If back on those days people were unwillingly to support the game enought to be a bussiness in that p2p model, What makes you think people will do it now when they didnt do it in the past?
