Make TE, completely reverting it to SOD, leaving only the interface, and the rest will gradually be implemented on its own. But I'm reading again about leaving the necropatch, chess clocks, and other things. Understand that any extra and unfamiliar detail, even if insignificant, that distinguishes TE from SOD contributes to the "rejection" of the average SOD player from TE. But when a die-hard SOD player understands that installing TE isn't that difficult, and that absolutely nothing new needs to be learned in terms of gameplay, then you can gradually introduce chess clocks, experience, and even the slow pace on the second level.
In short, I'm taking bets, gentlemen :D. I'm betting a case of beer that TE won't catch on if it's implemented using these already banal methods.
