I really like the idea of battle pass...cough...Nightwave, it provide a reason to return to the game more often and some good rewards for that, if you willing to do challenges. However i think that alerts should stay, be buffed even (cred and resources one). I don't need any catalysts, but average or new players can't get even nearly as much of potatoes as they can before, with normal alters, especially if they want to buy cosmetics and other stuff for wolf credits, which is bad, coz they may start to think that his is p2w game. Talking about cosmetics, with old alert system i can bet 2000p that i will get alt helmet for hildryn for time that frames was released till today(or atlest there was one or two alerts with that reward). But with new system i just can't get it coz i can't get it with random alerts and can't buy it via wolf creds, coz it's just not there and i don't know when it will be, and this is a bad.
TL;DR-Keep the nightwave as it is, it's good and healthy for the game, but bring old alert back and buff those,that rewards you with only resource and credit, like x3-5 time buff it.
