The change is sudden for everyone and not unfair to any single person IMO. The ones that supposedly have been hurt are the bot owners who had figured out how to automate the scanning of accounts and then autoattack every X hours right as the shield expired. This meant new people would never have a chance to attack targets as the bots kept finding more and more targets to add to their automated attack bots.
RC's isn't a DW issue, it's a Steem issue and until there is a good way to delegate RC's or RC pools it will continue to be an issue. I personally think that people should invest in Steem and not drop every penny into the games, but if you want to help this person out you can delegate even 10sp to make a pretty big difference as they aren't doing anything other then games on the blockchain.
This is the tool to use. Put in your account name and it will show any delegations you have currently out there, then under that list you will see where you can add a delegation to another person.

If you have issues using the tool just ask and I can help.
It worked perfectly, thank you my friend
Glad to help
