User blog:Fistful of Force/Cast heals early, not late.

There are a ton of fricking abilities that scale with missing HP. Nidalee's Takedown and Garen's ult just to name two. Not to mention the fact that there are also tons of abilities that lower heal power, like Fizz's seastone trident, or the summoner spell Ignite.

All of these things push towards one conclusion: Cast heal early, not later. If you cast heal later than expected you could lose a large amount of heal, or get completely screwed by a dangerous ability. It's ok to bait someone with heal, in fact, I recommend doing this, because even great players sometimes miscalculate and get baited. But as soon as you see that flash, nidalee pounce, tristana jump, or whatever, IMMEDIATELY CAST HEAL. Or you may end up losing the fight.

'''Shields too. Shields aren't like heals, you can't keep casting them until you max out. If you don't cast a shield when you take damage, that's health points you're never going to get back if you don't have sustain. In order to get the most out your shields, shield early, shield quickly.'''
