get some health regen. its a massive help against harrassment strategies. Monks are even better if you're a general and can buy Idols. health potions too. harrassing strategies rely on opponents who make themselves vulnerable to it. there's nearly always at least one in a match, if i find someone who can't be harassed i'll leave him alone and go pick on someone else. don't be that guy, because if you are you're gonna get harassed. 

Keep in mind HoL doesn't work in combat.  What this means is, even if they have super omega large health, they will still run out of mana fast if they have low mana.  If you are in combat, HoL doesn't do you squat.  And if regulus is doing that to towers, he'd be ganked in a hurry.  If the other team is allowing him, then they've probably already lost at this point in the game.

The only problem reg has with the HoL is UB spit and the occasional cannoneer or trebuchet interruption.

If you check your health/mana regen inside the character pane, it actually gives you:

+450 Mana per second
+300 Health per second

When used. So it's actually 4,500 mana.

I guess it's HoL's own 50% mana effect. Hm... that means Planar Battlecrown would be way, way more effective with HoL than Vlemish Faceguard.

This item is one of biggest reasons that burst damage > constant damage.

HoL should be removed from the game IMO, it is just plain ridiculus in some cases.

And yes, range-attack characters -Reg, TB, Rook(yes Rook is ranged) and Queen- greatly benefit from HoL.

TP Scrolls are cheap, there isn't much need for HoL. If there is, perhaps make it more expensive, or make its cooldown significantly longer so that you cant spam it. I mean 30 seconds, you just run in, lose health run back, heal, run in lose health, run back, you dont even care how much health you have anymore, it's just rather silly imo. A cooldown of say 60+ seconds would at least mean it had to be used carefully.

Meanwhile making it more expensive would mean people would perhaps get it later in the game, or be more disadvantaged in the lead up to buying it. It's just kinda rediculous that you can have someone at your portal flag on cataract, you run out hurt them, run your your crystal right next door, heal, and they've used HoL and healed faster than you have running 10yds to the crystal.

One of the key ways you could "come from behind" and win is that people have to stay in their lanes to push, and going back wastes time. HoL completely removes this strategic place in the game, and it just becomes, avoid absolute death, HoL, party more.

I personally don't think that's a bad thing.  As it is now, I rarely even get to level 15 (win or lose).  Most games seem a rush to Giants and then it's GG.  I laugh a little inside when I see builds that are speced out to level 20 with artifacts.  My own experience says that if you are level 20 with artifacts you're just toying with the opposing team and should have won 5 levels ago.

Once you get HoL, you can keep constant pressure on the opposing team with out having to retreat. Even with both sides having HoL, someone eventually has to turn and run (or die).  Normally the winner would regroup, wait for reinforcements, use pots, etc giving the retreating side a chance to regroup themselves.

With HoL, you can fully restore on the run (my biggest complaint) and since you won the previous fight and are now fully restored, the other guy has to fall back even he HoL's.  If he didn't win the first time, what are the chances of winning the second time?

I dont' think it's OP but I'd like to see it changed a bit with either a longer cooldown or not being able to move while restoring.  I think either one of those would help in be more inline with a 'Portable Cyrstal'.

I'd like either 1 or 2.  THANKS!

I think it should definitely be tweaked. I like the amount healed, but I think it heals far too quick and has too much of a short cooldown. Increase the duration that it takes to heal 3k by 5 seconds and increase cool down a tad. If you reduce the amount healed per tick, it would weaken the synergy HoL currently enjoys with oak's shield which is at the moment super powerful.

In those situations, you should probably go with Sigils of vitality and press the enemy. When they run, run into the towers. When they fight... hit the sigil, get 50% health back instantly, kill them (unless they are oak with HoL. )

Make heart of life freeze you entirely for the entire duration, and heal you until you get hit. I mean, actually stun you; no skills, no running, nothing, and no way to cancel, even if you get hit.

Then it's a real risk to use it; you can't just use a wand of speed, activate it out of range, and gain back all your health.
