I sure hope those who never played CoH pre-shutdown will be behind the content/powers. Sorry, no offense, but you will not capture what makes CoH, CoH. IP sell and all, with someone behind the wheel who has never touched the game before :/
Just remember, though, that it would be very possible to have someone making many design decisions that affect how closely CoT replicates CoH, and who has CoH experience... and who depends on someone without any CoH experience to crunch numbers. After all, it does not take any CoH experience to calculate attack chains, endurance expenditures, etc, to determine damage output for a set. Or damage mitigation for a defensive set (assuming a basic defensive set that doesn't use mezzing). What it does take, however, is a strong ability to crunch numbers.
THEN, you have to have someone with experience judge those numbers and decide how relevant they are, based on AoE sizes, likely team buffs to recharge or recovery, etc, and say whether a set is really weak or really strong. Number crunching is not everything. But if you're going to combine several talents, there are some sections where prior CoH experience is not necessary in order to properly fill the required skill set.
