make garen a tier 2 unit and buff him back up
you went overboard with the nerfs.
you nerfed him because of his interaction with morellonomicon in the same patch you nerfed the item itself and cut its damage in half.
as if thats not enough, you also lowered the drop rate for T1 units and made it much harder to get them to 3 star.
this is a classic overreaction that you do now and then in regular summoners rift aswell. you double and triple nerf a champion because of his item interactions, and also nerf the item itself on top of it all.
fact was, that garen was too strong for a T1 unit before the most recent patch.
however the whole group of knights also looks like this
T1: 
T3: 
T4: 
T5: 
the 6 knight buff is completely worthless, blocking 80 damage at a point where enemies crit in the thousands. because of this alone, knights shouldnt be nerfed until they feel like nothing more than champions useful enough for the first few rounds and should be a bit stronger in their scaling individually.
but that aside, there is clearly room for a T2 unit among the knights. if garens ability was too strong for a T1 then the obvious choice would have been to make him a T2 instead instead of dunking him with nerfs.
