If your skull is so thick that cant get "why?" Kaiator and Velik hasnt been merged then let me tell you the main reason, EME in the last year and GameForge now are waiting till the last second because they want players to "spend" money on server transfers before merging servers. And the only way to transfer is for someone to spend real money into that because even the vouchers you may find on broker, if there is some still, were bought in cash shop.
Thats a pretty cheap move from publishers and pretty much shows they rather milk away money from the few players they can and get the game shutdown in a short term than coming to a merge and try to retain as most players they can making more money in the long term.
Its just their business model thats that.
Well thanks for pointing that out so what i see is just a money that players do not want to spend on and rather looking for free transfers sorry to say that.
As you mentioned there is big amount of people from Kaiator already are playing on Velik hence publishers don't see there is an issue either they level up from 0 and re-gear or transfer. Another way to say is publishers don't see benefit from free transferring and of course first because there is already even a voucher you may find in broker that you can spend with gold which bought by another player with $$ also as you mentioned this is just their business model.
