Support. Imo smithing gold bars should give the same amount of xp/hr as does smithing iron plates in wildy, so hcim would have a chance to get easier smith xp without grinding coal.
Classic mode has its own perks. Reset highscores, sense of achievement, etc. adding "bonuses" to attract people to that game mode will imo ruin it. Otherwise lategame classic players would outclass every other type of accounts, so it would make it sort of a necessity to play on classic.
