1. means that sorcerers have more higher level spell slots at a whim. They can do it already but it takes time to convert and their is a loss in points. Casting strait from points means that font of magic is not required so sorcerers could start with 10 level 5 slots for example but switch so lower slots easily. That also becomes more complicated at level 11 since they magic font limits conversion to level 5 slots. If your allowing higher level slots and using the same pool then you end up creating higher costs that don't exist for those spell slots but in order to prevent 9th level spell over flow you make them so expensive that using high level spells basically strips sorcerers of meta magic's and lower level spells slots or you make them cheep enough not to burn all there sorcery points and lower level spells slots then they just cast 4 level 9 spells and destroy everything. --- Broken
You are mistaken in your understanding in spell points. Refer to page 288-289 in DMG
They can only create
1 spell slot for levels 6, 7, 8, 9 when they reach the proper level.
That is why I added the ability to create 1 additional 6th level slot at 19th level and 1 additional 7th level spell slot at 20th level. To differentiate them from other casters who may opt to use spell spoints.
2. So no font of magic and unless they picked twinned or something with high cost then they never use all their points resulting in a large amount of wasted points at higher levels and a bit of nerf... and why? Not much of an effect at lower levels.
Currently, at higher levels you regain sorcery points after a long rest only. You need to convert spell slots to create more sorcery points, depleting the spell sots and the number of spells you can cast.
By this method, at higher levels you could use metamagic more frequently during a combat. And with about 4 combats between short rests, you are not always going to have wasted sorcery points. I have played it already at levels 10 and 11 so far and like it better.
3. Again not font of magic, basically the same as 2 the result is again waste of sorcery points and nerfing the class at higher levels, will not matter much at lower levels.
You are regaining all expended Sorcery Points after a short rest. Again allowing you to use them in combat more without expending spell slots.
Economics 101 Supply and Demand. Limited supply of Sorcery Points but huge demand.
Font of Magic sounds good, but it forces a Sorcerers to use Sorcery Points to use Metamagic, replenish spell slots, and use special abilities. That is a lot of demand for a limited pool of points. By removing the ability to create spell slots and limiting its use to metamagic and special abilities only in combination with regaining them after a short rest lessens the demand.
4. This is massively broken if you can still make spell slots and if you can't then you will at higher levels just always be able to use sorcery points and meta magic. It would be the same effect of making meta magic static abilities with the exception of Twinned spell which is the only one that has a cost higher than 1 or 3(heightened spell). Twined being twice the spell level used, so just limit it to once per short rest and make the others automatic and remove spell slot creation.
You cannnot create spell slots with what I am currently suggesting.
(If allowed to create spell slots, then you are able to recover used spell slots uncontrollably, better than a Wizard and land Druid. Better if only for metamagic and special abilities.)
Again to previous point as currently written in PHB, Sorcery Points is in high demand: Metamagic, Abilities, and spell slot creation. To meet that demand, you have to keep converting spell slots to create sorcery points to meet demand. Not practical.
Then the Monk must be broken since they regain all Ki after a short rest. At low levels, the Monk can use Ki only a couple of times then must wait after a rest. The PHB Sorcerer must wait for a long rest or use spell slots, thereby limiting him/her to cantrips or use the sorcery points to regain spell slots and being unable to cast metamagic or use special abilities.
Sorcery Points, as Ki, makes this class standout among other classes. Why shackle the Sorcerer?
