At its current pricing, it will cost around $160 for ALL the mercs in USD that is like purchasing four AAA games that have just been released.
Or 720,000 credits which at an avg of 150 credits for a 10 minute obj, relates to 4800 games. 4800 games at 10 minutes a pop is 48,000 minutes or 800 hours.
It might just be me but I believe 800 hours or $160 is a little much for 19 mercs in a f2p game. You will lose your whole fan-base except for those which have no lives, or have large sums of cash to throw at a game. You’re only argument could be your f2p model and you are trying to ear money or you don’t want the players to get bored. If your community gets bored because they have all the mercs that’s more of an underlying issue with the game not the mercs pricing. Look at t2f arguably the most successful f2p game out there and they have had the same 9 classes since its release 8 years ago.
If you want to make money just let nexon do what they do best and rape our wallets with cool gear. Just make them cosmetic only no better stats because no-body likes p2w. And make it something like $30 for all the mercs like in a bundle.
All in all get your **** together SD.
