That's the reason why I still prefer DA black, just because of the finishing material.
Anyway, for myself (my palm), Ikari still the best ergonomic mouse.

lol every inch of rubber coating will have wear and tear

This happened most probably is because the unstable and high power consuming in lycosa.
The power regulation system for the board is not so stable and caused the board having the insufficient power problem then cause the stuck. In short, the power level stuck at the level around threshold power, make it unable to work properly but not also not restarting.

Update firmware may help if the newer firmware reduce the power consumption.
Try another solution if the firmware doesn't help, connect it to powered usb hub.

That's not true.
BW is 2kro.
Although most of the key combinations will work but that's due to razer separated the key registration into large number of different zone (this is not the proper terminology, just my understanding), indeed, within each zone only 2 keys can be register simultaneously.

Try press "ZXC" together, some times it won't register.

yes, it is 2kro.
But so far I only know ZXC not working together.
I think you are fps player, I just tested on my own bwu.
