So I really like playing Pathfinder, but there are a massive amounts of problems with the system. I'm really excited for Pathfinder 2 as an update, so I'm really hoping the dev team gets PF2 right.
The most powerful abilities in pathfinder usually revolve around a couple of key concepts:
1. Action Ecnomy
2. Controlling Space
Even from level 1, this is readily apparent. A wizard walks up to some goblins and functionally kills them all with a color spray, but a fighter has to hack and risk injury one at a time. A levels 10+, it becomes absurd. A wizard can throw save or die fireball with dazing spell, and be protected from attacks with emergency force sphere. Or if you want to win immediately, you can cheat out a geas with limited wish, maybe without even paying with blood money!
I understand that combos are going to exist that are powerful, and because of Paizo's business of releasing books monthly, it's going to be hard to keep control of everything. It's the same problem MTG has, they print so many cards that infinite combos sneak through all the time. I really want to want to stress that right now Pathfinder is (I know this is thrown around a lot for minor balance issues but it is really true here) broken as written. Anzyr has what a high level wizard looks like in one of his posts and it is use the rules of Pathfinder as written, and pretty much as intended.
Spells like limited wish and wish that let you cheat out very long cast time spells are too good. I am kind of horrified that there will be a 10th level of spells because of how crazy the 7 8 and 9 spells already are.
Metamagic is too powerful in Pathfinder currently. Quicken is incredible action economy and Dazing spell turns you in a save or die machine.
Many status effects are essentially a save or die. If you nauseate someone, they are basically dead because they only have move actions. Stunned is the same thing, blind for many creatures makes them worthless, exhausted is brutal, dazed might as well be dead. The powerful status effects are functionally the same as having your character just be dead. Please be careful!
If you put an ability on an outsider, such as wish, that also means you are giving it to wizards. If you leave planar binding in the game, any time you print an outsider you are giving wizards access to a new body with spells. If you give the outsider a spell above their caster level, like wish, you are letting wizards get wish a lot earlier in the game than generally intended.
There is a lot of minutiae about why spells are too good so I tried to cut it down a bit. I did a re balance on my own for my games but I am worried for PF2. I'm not even getting into the issue wizards have with class identity and flavor. If you have an questions you can ask me and I can get into a bit more. Hopefully all these issues are addressed in PF2 and I can feel happy picking a wizard!
