They should increase the chance of radiant drops as we have to start arcade at depth 18, and we start getting rad's at around depth 26. We have to waste hours to get to depth 26, and yet we get only three or six rad's per depth. Even in Vana you can make around 20-30 rads, but thats rare. Vana doesnt have so many boxes and you get like 3 or 6 rads per depth. After boss fight I mostly get like 15, but again here after an hours work. I'm not complaining or anything. The shinings, glowing,etc. system is pretty good. You can get like 60-70 shinings in a tier 3 arcade run. I know that DaN drops ALOT of rads, but for me its TOO difficult. The radiants drop rate should increase a bit.
