First of all, TC has always been stronger than f4, it's just a low chance of getting it so it wasnt worth spending a GCD unless it was a slow tick. But if you got it you shouldve used it and used some brain power to not be retarded and skip a f4 if you have to.

Now its a 1-0.90^6=0.468559 (aka about 47%) every thunder1 that you get a proc that has the potency of 710-(40*x), x being the amount of ticks you have left on your thunder. Not to mention every time you TC the proc rate goes up to 1-0.90^8=0.56953279, aka about 57% for at least another proc during the whole new thunder duration.

Just stop being retarded and skip a f4 and go into UI earlier to refresh enochian, it was worth it before, it sure damn is worth it now. It went from like 26% to get a TC from t1 to fucking 47%, that's one hell of a buff. Not to mention getting off a TC means you potentially don't have to refresh it during UI at all.
