Tryndamere's ult should be a passive

A skilled Tryndamere will, at most, waste .5 seconds of his ult. By making it a passive, he will no longer be able to strategically withhold his ult to force another 2-4v1 fight as he splitpushes and instead be forced to wait for it to come off of cooldown. Although this eliminates the slight factor of human error in casting his ult, it is, once again, largely irrelevant as a Tryndamere with even basic experience should understand how to use it. You now only have to send multiple people to deal with him every 110/100/90 seconds rather than as soon as he respawns since you're unsure of if he'll decide to use his ult or not.
