I'd want to help Bless stay alive, but I disagree about making faction transfer possible, people would need to re-do all quests for all their characters, basically meaning to restart from scratch, which is dumb, and they'd need to leave their guild and etc. It just wouldn't work out well in Bless. And races from Union and Hieron aren't the same so it's another problem.
And a single server per region would make it impossible for players to have a character in both factions, thus removing liberty.
The 2 servers per region we're getting in late July is a better decision. Now we need optimization to be better, cheats/client modifications need to be fixed, hackers need to be banned, most stances' combos need to be remade to be more intuitive and unique (why not changing skills' upgrades by the way, +5% skill power on a CC focused skill is kinda dumb and boring isn't it?).
Then we need to talk about trading, which is a big reason a lot of people left Bless.
Personally, I'm not worried about content yet, we already know content have been made up to lvl 50 in the past, just need to wait (probably a couple of months) past full release.
I think Bless can still survive if it fixes optimization/cheats quick (in August) and then achieves to maintain a good balance between classes in PvP and PvE.
