Since which patch did all champions start having 5 bars of HP instead of 4. I.e. Soraka now has 4 large bars and smaller bar, instead of just 4 bars.

Each bar represents 100 health. I'm not sure if soraka's health was buffed, but it may just be more defensive runes and masteries.

no, like all champions have at least 4 1/2 bars of hp now.

It's true. Instead of just getting a whole bar per 100 health, if you have say 450 health, you'll have 4 and a half bars. It's a pretty cool change.

it's a positive change. it more accurately depicts a champions hp
