The problem isn't constitution per se, but again the armor/protection system. Too often the decision about win or loss is done way before HP comes to play. So why bother with it at all...
That needs to change.
But in general I have to say, that I dislike that there is just one attribute at max 2 that are interesting for a specific playstyle. All attributes should have an impact, imho. A useless one should actually be the exception.
Again this is a thing I love about The Dark Eye/(Das Schwarze Auge).
There the base attack in melee for example is calculated by: (stregnth+courage+agility)/5
Same goes for base defense: (strength+agility+intuition)/5
And many other alike, like magic resistance, evasion, ranged, stealing, sneaking, endurance, magic...
In other words a lesser impact with greater versatility that evens out the extremes.
This has been brought up to death during discussions, if CC is 100% at 0 armor, your hp is utterly worthless, because you'd be chain stunned anyway. Is why people can kill the 11k hp troll just by chicken/stun him until death. But alas it was willfully ignored.
Everything in the game right now is still a dps until armor down then autowin the game. Plus now late game absurd stats one shotting everything with a sneeze, this applies to both sides.
