Even if you ignored the fact that 95% of the current active clanning community wouldn't know what to do - it's lacking multi-combat zones and clans simply won't go back to that. Although, even if you refer to going around in single teams, 80 mage+ on RSC is insanely overpowered if you know what to do.

People who played it before do enjoy playing classic, I expect to see some clans who have old school members with RSC accounts maybe have some small fights. Would be cool to see one posted on tipit if any clans thought they had enough decent levelled RSC accounts to do it. I wonder if BK probably has a fair few people with accounts still if any clans did think it would be worth trying.

 

On a regular basis I expect to see very little difference though.
