||At the moment, it's a clutch level 1 purchase, the mechanic Dr. Mundo is based off of, and the single weakest form of sustain.
Yet, Exalted With Baron Nashor provides so much HP5 that it creates an autowin situation for the team that it is on, granted that said team isn't subject to large amounts of instant damage.
Here's a list of every item that grants HP5, and how much it grants.
- 15 Regrowth Pendant
- 20 Warden's Mail
- 8 Rejuvenation Bead
- 15 Tiamat
- 40 (+1.75% of max HP) Force of Nature
- 25 Randuin's Omen
- 30 (+10) Warmog's Armor
- 15 Philosopher's Stone
- 25 Eleisa's Miracle
- 30 Shurelya's Reverie
- 10 Emblem of Valor
- 15 Locket of the Iron Solari
- (+15% HP5) Spirit Visage
- 8 Doran's Shield
So, let's get down to discussion.
Health Regeneration per 5: A stat that is meant to have value in its utility over time, but actually is completely worthless in practical application because Riot Games has decided that it promotes passive play and undoes any reward that aggression might have for the players in lane fighting against someone with enough of the stat to matter.
On top of that brilliant philosophy, HP5 is the single weakest form of health sustain. The Regrowth Pendant is infamous for granting more health to the user than a Ruby Crystal given an entire minute's time. Of course, this is pretty easy to accomplish for most players, and is a common choice for lane sustain. Then, I ask, why does Darius, a champion with no sustain of his own, buy a Ruby Crystal? Because that sustain over time doesn't matter when he can just get in his enemy's face, kill them, and go back to the summoner fountain for tons of healing.
This brings us to Turrets. Towers, Turrets, Statues That Shoot Light Balls, you know the kind. These things inhibit aggression in certain areas of the map, allowing players that have purchased Health Regeneration per 5 to sit around and heal passively. This is the largest outstanding reason for why Riot Games has made HP5 as weak as it is, but it is far from a good reason.
HP5 is not something you build items for. Rather, it is something you pick a champion for. If you're not playing Dr. Mundo, Singed, Vladimir, or at least Garen, your HP5 doesn't matter. In fact, if you're not one of the mentioned champions, putting excessive emphasis on HP5 in your item build is mortally stupid.
From a balancing perspective, HP5 requires no interaction from the user to gain its benefits. You buy HP5 items, and then that green bar fills itself up more quickly. Then, I don't know, Renekton comes along with his Bloodthirstier and chops you to bits while healing for a lot more than what the regeneration you have is providing.
Even as Riot Games looks at gameplay behavior and decides, "Player X is just sitting under their turret and passively healing so much that the other player might as well not even try to kill them," in reality, the situation is more like, "If player X doesn't sit under that turret and passively heal, the other player is going to kill them."
Does one honestly think that a player in a MOBA game is satisfied by sitting under a turret, afraid of direct confrontation for fear of death? It appears that one does. Unfortunately for the rest of us, that particular "one" is the governing body on item balance.
The innate passivity of HP5 rules it out as a valuable battle utility outside of obscene amounts.
I'll be the first to hate on Singed in lane as he passively heals you to death and runs around without dying, but I shouldn't feel bad for buying a Regrowth Pendant on 90 other champions.
