As a ride leader and sweeper I’d like to see the Hammer Time button replaced with a Help button to make it easy for riders to request assistance. People struggling off the back may not be able to type to request assistance or there may be language issues. A Help button makes it easy.
This will also help sweepers identify those that need assistance. It can be difficult to know whether someone has dropped off the back for sprint practice or whether they are genuinely struggling. This difficulty is magnified when those riders don’t or can’t communicate in game.
Perhaps if a rider presses the Help button a special icon appears next to her/his name in the rider list like the a sprint jersey and a thumbs up button. If a sweeper clicks the Help icon the two riders can be guided to each other or at least known to each other. Keeping each riders name visible to each other and static in the rider list may be one way to achieve this.
Perhaps also reward sweepers with extra drops or XP for their efforts.
