Yeah.. thanks for correcting. I realized i used multiple negatives which got me confused as to what i wanted to say. Basically, what i want to say, is that IAP isnt necessary.
To add, when i posted those previous comments, i was already able to upgrade each character's second weapon once, and the sniper's weapon twice.
And the game has a good balance in terms of difficulty. Forgetting to move or use a skill in the right time can get one of your Nuns killed, and focusing on moving them and using skills isnt so easy to do either.
The tank Nun is reaaaally tough, and her taunt does a pretty good job of keeping everyone alive longer, enough for the healer to heal everyone back up to full.
At the first chapter, you only have 2 Nuns to control. You a new slot for a nun to control after you kill the first chapter boss. I was using Sniper and Healer during the first chapter. Now that I have unlocked a third slot, I used Sniper, scout and tank, and I never found the need to use the healer as long as I keep my squishies alive with ther skills and with Taunt.
Almost done with Chapter 2, and im surprised this game is taking a lot of my time more than Punch Quest, NYZ2 or Shardlands. Makes it hard for me to choose a GotW.
