Ugh... Respec just should not cost anything. That's a great way to kill replayability. Look, if you make people free to respec, they'll be more likely to buy a wider variety of guns to fit all the new playstyles they can support. So it's in your best interest, monetarily, to at least give us that freedom.
Guys complaining about survivor searches: It's not broken or imbalanced. You just need to work out the proper ratio of survival rate to find chance. Melee skilled searchers seem to work best, while shooters improve survival chance but not evasion chance.
I played this game on mobile up to (so far, more to go) level 110. It's worth the purchase, seeing as you can transfer save files between mobile and here. So while I'm at my computer I can play this and chat, and then keep doing it while traveling should the fancy strike me.
