I play carry champs and I hate true damage

I really hate true damage, it doesn't involve game knowledge, true damage in any capacity is extremely unhealty. Build HP against it? Ok but the amount of HP that can be built is still not high enough to deal with true damage because HP is a stat you're supposed to increase via EHP.

true damage essentially has two issues, first it makes tanks useless (In my book whatever, I hate tanks but tank players probably want to play their champs), secondly it makes counter itemization amount to HP stacking

for AD damage reduction items we have a wide variety of choices, some might say too many choices but i disagree for a few reasons, for AP damage reduction we're pretty limited.

Why not buff tanky items across the board, including tanky carry items, and also add some more AP-Defensive items. Let carries be tankier, tanks be tanks, and let bruisers still be bruisers. outright remove all instances of true damage from items and runes.

"Wouldn't this mean that a tanky build ashe will take no damage from a full tank maokai?" Nope! because there will actually be AP bruiser items (Ap-defensive), in addition if a maokai builds full tank he'd have all that damage reduction

"So people would still go full damage or full tank?" well if done incorrectly then yes, but if done correctly then these defensive items would be viable alternatives to full damage builds.
