Pyros has issues. It's not terrible, but the logos system has caused some problems. A lot of people farm bunny fates for chests, which mean less people spawning NMs. Pyros crystals seem harder to come by because of the slower NM spawning. A lot of logograms are hard to get, requiring a lot of luck with a gold chest at times.

And speaking of slow spawns, we had several groups of people prepping Penny through two heat waves today for hours and she never spawned. Next heat wave is in 6 hours. It's terrible.

Map design is better, leveling is better and low level aetherytes are good. But it seems like all the ridiculous RNG is specifically designed to drag the content out as long as possible.
