That could also work, but again that also runs into the issue of being really affected by armor, which comes back to the original issue. While I was doing the math, I also looked at bonus health ratios, but the result was that the numbers would risk either spiking too hard at high health values, or not being good enough until enemies build tons of bonus health (the above true damage already provides by far the best sustain against tanks).
