Like it was stated at BlizzCon there will be no crossover in rewards between Retail WoW and Classic WoW. I don’t think there is any need to change that stance but I appreciate the post OP.
I think its fair to ask for an opportunity to earn those rewards again however I don’t think it should come at the cost of diminishing the rewards that players earned years ago and cherish. I think the opportunity to earn and have them exclusively on Classic is fair because its staying on Classic itself. I think any more crossover than that could be damaging and lessen the value or prestige of those rewards.
It’s a pretty solid philosophy at the moment that there will be zero crossover of rewards.
