Rune Healing

[Estu]

I don't know whether this is a bug or in fact classic behavior, and I know that this is nothing new to the forums, but rune effects heal. In particular, the polished granite tomahawk's proc, which shields you from some amount of damage (seems to be around 25-50 hp), actually heals you for every point of damage you take while it's in effect. Does anyone know whether this is classic?

Anyway, the effect of this is that warriors actually make surprisingly good soloers at low levels with some relatively cheap gear. From 1 to 9, a tentacle whip does good by you; then at 10, the PGT starts proccing, and with my warrior's DEX of 120-ish, it procs often. I can pretty much chain dark blues, occasionally killing a couple of greens to heal up. At level 13 just now, I went to Crushbone and gained an entire level soloing light and dark blues in two hours, holding my PGT in my main hand and an Obsidian Shard in my off hand. Now, don't get me wrong, I would have liked to group, but the zone was not exactly hopping at the time. (However, I did learn a trick: hopping onto the roof of the slaver hut.) Just thought it was kind of cool!
