STOP reducing the Kuva Lich's anger plz it's really stupid and time wasting

[ArchWu5]

Since we got the Kuva Lich I've finished 6 Liches,however,each of them was finished with a long long process of accumulating the anger,especially when I know the correct Requiem Mods' name and order,normally the Lich is 5 rank and each time I failed to slay it the anger of it will reduce and I need to spend a lot more time to accumulate the anger to let it appear again.The recent 3 Liches cost me almost 1 hour or more to make it very angry and appear in the mission so that I can slay it with the correct Requiem Mods in correct order.It's really tiring and time wasting.I hope that this reduction of the anger can be moved.

My guess is when you get the new frigate system (Forgot then name) in you be able to hunt the liches instead.
