I know several people who stopped playing Pokeheroes because they
were frustrated of the non-appearance of a Shiny Mega. I suggest,
that every 5000. or 5000. th egg in a chain should be guaranteed to
be a shiny mega, , to stop frustrating of the user. You are very
restricted during a chain, for example, you cannot hatch Legends,
and this also leads to frustration if the chain grows too long.
Perhaps this would decrease the price of shiny Megas a littele, but
this is nothing against the mass- finishing of frustrated users.
