Undying rage and Battle fury swap places
#Current:
##Battle Fury (passive)
Tryndamere receives 0.35% bonus critical strike chance per point of Fury he currently has, for a maximum of 35% critical chance at 100 Fury.
##Undying Rage (ultimate) Cooldown: 110 / 100 / 90
Active: Tryndamere instantly receives Fury and becomes immune to death for 5 seconds during which his health cannot fall below 1. This move is usable even when stunned, silenced or suppressed. This ability has a 0.5 second delay before activating. If Tryndamere is below 3% health when Undying Rage ends, it will heal him to 3%.
#Proposed:
##Undying rage (passive)
Cooldown: 110 / 100 / 90
If Tryndamere would take lethal damage he automatically instantly becomes immune to death for 5 seconds during which his health cannot fall below 1. If Tryndamere is below 3% health when Undying Rage ends, it will heal him to 3%.
##Battle fury (ultimate) Cooldown: 50 / 45 / 40 / 35
Tryndamere gains one rank in this skill automatically.
Passive: Tryndamere receives 0.35% bonus critical strike chance per point of Fury he currently has, for a maximum of 35% critical chance at 100 Fury.
Active: If Tryndamere is at less than full fury he instantly gains 25 / 50 / 75 / 100 fury.
#Reasoning:
QoL change that makes it so that he can't fail to activate his ultimate in an important team fight, and he doesn't have to build fury before the fight begins (off of a jungle camp for example) to have fury for the first half of the team fight. This change also allows him to top of his fury if he ganks after leaving a jungle camp (assuming he doesn't dilly dally), which makes him a slightly better ganker.
Other champions that fail to use their ultimate properly would see punishing consequences, but none as much as Tryndamere, who's entire functionality is contingent on using the ultimate before dying to burst. To compound that problem is an immense pressure to not use the ultimate too soon because of how precious those fractions of a second are to Tryndamere. It may be an expression of skill differentiation (or specifically, reflex differentiation) between good Tryndas and bad Tryndas, but the additional volatility and unreliability that this adds onto Tryndamere's gameplay isn't worth it.
