Hey everyone, I'm a fairly new player, got 18 girls in my harem now. I recently got Taria the champion which is great for me as I am a charm player. However, the upgrade costs for her are getting horrendous (at least to me, at level 67. 9 million for the 4th star).
Since I have read that upgrade cost as well as the drop chance of girls correlates with the number of girls in your harem, I started to wonder if I should play the trolls for event girls at all, if I don't really need the girl (like the current troll girls right now from the christmas event). Is it better to just wait for a girl I want for my team? (Fanny and Fione, Metal Noemy or Summer Geekette in my case)
I don't spend money on the game, so free Kobans is all i have. I dont want to miss out on one of the girls I want due to super low drop chances when i finally get the chance to obtain them.
