its not a bad option if u need that one extra point to lvl up but the cost of the point is so high that it really does defeat the purpose of it it is not bad for the high level players that can farm rc from quests especially when u get ur xp up there u know it takes a while to level up a level when it takes 100k-200k per level several times to go up one overall level so it would b worth it then but it should have a better explanation page on how the game works for the new people that signed on cas when i first started on the game i didnt know the importance of rc and used them to buy gold and energy
