Twisted Treeline Bugs
These are some pretty big bugs introduced last patch that I am VERY surprised aren't being addressed this patch.
Turret Armor.
Madreds Razor.
When enemy minions are around, turret armor drops to around 0 or 8, depending on how many minions are around. Turrets die preeeeetty easily. This has lead to an interesting shift in the strategies on TT (attack speed with no armor pen or even damage is pretty brutal), it is pretty obvious that this was unintentional.
Madreds razor is still on the map (as is the spectral lanturn)... And it's build costs are hilariously screwed up. To get Madreds razor, you just buy a dagger, and upgrade it for 0 gold, getting the FULL benefits of the pre-update jungle item. It's pretty OH-PEE.
I havn't seen anything from Riot about this getting fixed, but I had a hard time imagining they weren't aware of these problems... Until I read the patch notes for 4.21, and saw that neither of these were fixed. Don't get me wrong, I am STOKED about the new jungle camps hitting TT, but comon...Fix these bugs please!
