about learning anything:
according to the rules the sorcerer may learn aquired spells that are not in the sorcerer/wizard list. It does not specify which spells those should be then, nor if they should be arcane.
I must admit after re-reading the RAW the rule can be interpreted in various ways, and I now assume the author was referring to custom-made spells by the DM or spells from other sources.
About the reason why I want to play this class:
I have played a druid for quite some time, and one of the things that has always irritated me was seeing the party sorcerer's casting whatever spell was necessary at the time, while being stuck with unusable spells myself.
Now that I have the chance to play something simmilar in a new campaign, I started looking for a divine class with full spontaneous casting. When I couldn't find what I was looking for, I decided to build one myself.
The point was to not re-create the druid or cleric, but to create a sorcerer that casts divine spells instead of arcane spells. Since divine spellcasting is not hindred by armor, i could have included armor feats, but decided not to.
Instead, if I would like to wear armor later in the campaign, I can always buy armor feats, or, even better, take one or more levels of fighter..... If I want to focus on spells however, those feats would go into Meta-Magic feats, and fighter levels would be a matter of wasting XP.
