This is a little spreadsheet that I put together for my Ranger. I find it extremely usefule as I often forget what spell replaces the previous one. I also have a tab there for poisons. Nice to have a quick view for all poisons when you are looking for just the right one for a particular fight. If the spell tracking could be added to the knowledge window or somewhere else, that would be extremely helpful. Some of the spells are never replaced, only get better as you advance, you will notice that those remain green. Anyway, if this could be created for each player type and added, I would be forever thankful.
