Ok, but one could argue the very same for Health stacking early, especially with large health items like Warmongs.
So are you telling me that Health is OK to be powerful and lane warping, or is that next on the chopping block.
Warmog's Armor is not as powerful as most people make it out to be at the moment - However, the incentives to build it are there, because there is no readily apparent counter that your opponent can take.
Essentially, let's say I gave you two options:
Option A is generically strong and has no real weaknesses.
Option B is situationally strong and has a real weakness.
In general, players will tend to gravitate towards option A unless
option B is so overwhelming powerful that it dwarfs option A's power. Part of this is the natural human tendency for risk aversion - part of it is because it you can't point out a situation where something is bad - you automatically gravitate towards that because there's nothing telling you 'no'.
We've seen this effect before on the more generalized fighters like Irelia. In order for a champion to be seriously considered versus Irelia - their strengths had to frequently be far more dominant than Irelia ever was to be considered "viable" - when you could just choose Irelia and have a safe time. In general, whenever we've done Option B without adding a real weakness to Option A - the results that came about are frequently more toxic or infuriating than Option A ever was.
For example, a lot of Riven's number tuning and damage was tuned to overcome Irelia's sustain strength - and making her all physical damage so that armor was an effective counter.
What this meant was that Riven was simply more toxic and frustrating to fight against than Irelia ever was - because in order for her to be played, she had to overwhelmingly
destroy Irelia for people to justify picking her when she had clear counters.
