Tryndamere's "Undying Rage" isn't really undying
Tryndamere's "Undying Rage" lasts for 5 seconds, and has an extremely long cooldown of 90 seconds at max rank. This isn't undying. At max rank, Tryndamere's rage will have only an 18% uptime. This needs to be fixed, for the sake of lore and consistency. His "Undying Rage" should be up 100% of the time, not 18% of the time (at max rank). To fix this, I suggest Tryndamere gets a small change. I suggest that Tryndamere gain a passive on his ultimate making all types of crowd control be unable to affect Tryndamere's ability to cast his skills. This passive should be up 100% of the time once Undying Rage is leveled up once.
Thank you for reading and upvoting me to help keep lore consistent.
