I apologize; it's been a very long time since I've updated the game. I still want to complete the game. It's still in production, progress is just very slow.
Mapping as been completed, and now I'm going to do a balancing sweep for the already completed changes. Here's what I'm planning on:
-Base HP will be increased. This will stop characters from getting one-shot without defensive buffs and make fast monsters more manageable.
-Low-level elite encounters won't be so much of a pushover anymore and will be more interesting to fight.
-The first dungeon (Shadow Caves) will be a bit more forgiving and will have smaller monster groups.
-High-level characters will generate AP at a faster rate.
-Lots of small tweaks to monster balance.
Now would be the best time for suggestions if you have any!
I think that having high level characters generate AP faster was the best balancing move here. Previously, mages had the advantage once they got access to tier 2 spells. Both mages and warriors would get moves that cost more and are more powerful, but where mages also got more MP to cast their more expensive spells, warriors got just as much AP as always.
I think you're on right track with the rest of the changes as well.
