I like the idea of thornmail changes but I don't like the idea of grevious wounds
Because grevious wounds shuts down lifesteal on more than just ranged ADCs. And armor stacking is already a really efficient way to reduce lifesteal tanking because lifesteal applies after damage reduction (or whatever order it applies in to significantly weaken LS but I believe it's after damage reduced). I think this keeps the same bland problem thornmail has now that makes it really underwhelming. Sure you get 100 armor but you get no HP and in the long run, there are far better options for tanking than 100 armor/no HP. And the passive now or a grevious wounds passive would feel pretty underwhelming for such a stat.
Many champions kinda have LS as an identity to their kits that aren't ADCs and an item like this would be really punishing to them, I'd say unfairly so.
I would like to see the item gain more interesting gameplay while having moments of vulnerability and moments of clear strength. As an example, I'd say after being auto attacked or taking any physical damage in a certain duration, the item begins to store that energy and reflect it back in damage after a certain threshold on-hit to anyone who auto attacks the thornmail holder (think of the mirror shield in Zelda OOT when fighting the witches).
There would be a clear glow or shine to the champion when the reflection is ready to pop and start returning a lot of damage and then this goes on cooldown for 60-70 seconds (almost like an AD hexdrinker/maw). This means if you want to continue focusing the tank, it comes with penalties but it also means focusing the tank isn't instant damage taken, which made it a frustrating item to deal with during cinderhulk meta. And if you elect not to focus the tank, the tank gets longer duration of life and longer zone control but in every situation, the item rewards proper gameplay rather than just being a punishment for focusing the champion with it or a punishment to the champion wasting 2300 gold on it when it's weak.
Just my two cents, and even then I'd rather not spend my last two pennies on the current thornmail. There's this grocery store by me that has a mechanical pony and rides only cost a penny, I'd rather take two rides on that and bust jewels.



are examples of mid laners who do not build Morellonomicon) or the carry who is so focused on either flat armor penetration, crit/AS synergy, or builds
instead.
and
passive?
etc in this argument.
ITEM.
.
. Some OnHit magic damage coupled with some %damage return. As an added bonus, it would have innate synergy with Wit's magic resist shredding.
, you don't want to be forced to focus that either.
Thornmail will reduce the lifesteal and now we have to build
MR items
that also gives lifesteal... what a bummer -_-
.
. The other problem with building thornmail is u have to hope the people who it counters is stupid enough to target u aswell... no problem for
decides to say screw
and flash/ghost past him while he charging that Q to dive ur
... Ur pretty much just screwed.
