I had an hour or two to make this extremely simple spreadsheet which models any given hero from a pure DPS stand point, take it for what it is, it might be fun for some of you to actually play around with it. Any comments, improvements or bugs you find are appreciated!
What it does
It allows you to calculate your damage, attack speed, how hard your hero hits, DPS, total cost of your items and more.
It allows you to answer questions like, should I go for riftshards or savage mace to increase my DPS? What will a shieldbreaker do to my DPS? How much will my DPS increase in percent if I get item X or what is the most cost efficient item from a pure damage stand point?
What it doesn't do.
It doesn't quantify the benefits aside from their pure damage. For example FWS is just a damage item without the added orb effect since it's quite hard to give a value to an effect like that, apart from the pure damage it gives.
Changelog
v0.11 - Corrected the attack speed for server frames (cf [1]) and improved the calculation of "Points" by removing non-damage portion item costs in the calculation.
v0.1 - First release.
