It really does not make sense to me that Sic/Ready recast timers are so long.
It was much improved when the ready command was added. However, it doesn't make sense for this time limit to be imposed. Why shouldn't the limiting factor be TP like automatons?
The Ready commands are not even so powerful. Depending on how much haste I have, I can WS many times between pet being able to use a ready move. A mediocre/poor WS will do more damage than the best DD ready moves. a Good WS w/ atma will do a good 2-3x more damage.
It seems it would be much more appropriate if TP were the limiting factor.
