Crypto RNGs take a toll on the system as they can drain the entropy pool. There are attacks that involve draining entropy pools, which can be mitigated to some extend by only using crypto RNG when necessary. Why do you say there is no forward secrecy? Every single message is encrypted with a new key, so the only viewers are the folks the message is explicitly sent to. You say this is less secure than OTR, but I fail to see why. I'd say the reverse is true.
