There are two considerations here - levelling and end game. The issue is WoW’s api was changed to not think about spell ranks between classic and now. GetSpellID() takes Fireball and Fireball(Rank2) And If rank 2 is your highest returns the same ID. Endgame wise it’s pretty simple. Check if a rank has been set when saving the macro and make sure that that version of the spell is stored. When reading, include the rank. Levelling though gets a bit more interesting. It will take months for someone to level. Currently, if they don’t have a spell it will just skip. But should Rank4 Fireball downscale to Rank1 if the player doesn’t have Rank4. Logically I think it should but can this be done via the API. Also when a player learns new spells it should check if a higher rank is now available. Should it then up rank automatically or should it prompt to uprank? Should the user be able to review each change? This is a ton of time lost that the user could have spent playing because you brought Fireball Rank3 The easy answer is to do a /use Spell(Rank) as GSE won't try to convert that to an Id for down ranking but that doesn’t work in castsequences Need more thought/input on what to do here.
