About orphan blocks
They appear due to the fact that the network hashrate is calculated incorrectly and difficulty does not increase
In order for hashrate correct calculation, it is necessary that none of the pools has 50% of blocks
You are not forced to mine on the pools with the highest hashrate
There are pools with the low hashrate
Start mining on them, smear the hashrate of the network more evenly and everyone will be happy
There is pools:

Raise their hashrate
If you don't want to mine on this pools, don't cry that there is so much orphans
There is the case that the 30 seconds per block increases the amount of orphans, but not significantly
About the estimated profit, it is also calculated based on the hashrate of the network
Network hashrate is calculated incorrectly, the estimated profit is also calculated incorrectly
There is wrote above, that the pools were not working.
Stratum worked. Web interface and cron was glitched
This did not affect the payments of the mined coins.
Everything was paid in full, however with the delay.
