So far, the items available very much match the item library many of you are probably familiar with from Izanami's Python "All Jobs Damage Simulator and Gear Sets" - which means you are largely limited to building TP/Engaged sets and weaponskill sets at this time. Using the gear data he compiled was the easiest way to get started, but I hope to add more items making it possible to build and compare other sets (eg precast and midcast sets).
Also, eventually I hope to add a way to save and recall sets you've built, as well as an "export to lua" feature. Other ideas are welcome. Hope you enjoy, and please share feedback.
