Make Tryndamere unique

he's not unique as a melee ADC, yi already exists. therefore riot should balance him around being a melee assassin. assassins aren't kitable, so why do we allow tryndamere to get kited? tryndamere needs buffs to make him fit as a unique autoattacking assassin, not a generic melee ADC. here are my buff suggestions to make tryndamere more assassin-like:

Gains tenacity with fury gain 1 ms per 1 fury unaffectable by hard cc during ult spin has no cooldown during ult facing away enemies will be stunned instead of slowed with W. facing toward enemies will be slowed. both for the same duration as now. tryndamere now stealths during his ultimate's duration

now before you say tryndamere will lack counterplay, i'll say that that isn't true. you just need to kite him before he ults then use a pink to soft cc tryn while he's ulting. soft cc will actually be his only counter, making him a very unique assassin.
