I would recommend you use
this tool if you have time to fix the tooltips. It makes the tooltips look better and is easy to use.
Also, if you downloaded that, I fixed the Giant's learn tooltips, download the attachment and open it up with that tool. Just copy the Source (the one with all the weird characters) and copy it into WE. Also, please highlight the tooltips with a nice color, I have no idea what the tooltips for some things are ATM.
Also, you may want to look at
this. It teaches you how to make the hero's icons fit where you want them to be, instead of somewhat randomly.
I could redo some other hero's tooltips if you want, just tell me which hero and the tooltip for each spell
