We've had players ask us to make the essence mining section of RC more interactive (and other players asking that it be left alone). In this update, it's not changed. That doesn't stop us changing it in future - and I'd like to thank the players who've sent me proposals for exactly how they'd like it changed - though there's very much a split in opinions here. Essence mining was never exactly an interactive activity before; in fact, that's why we've generally added features to stop you having to mine pure essence yourselves anyway. The rest of the RC process is considerably more click-intensive, especially if you're chiseling while running for an optimal XP rate.
