That really nerfs humans, does custom lineage get theeir feat at 5th too? The other stuff I could live with.I kinda like these House rules:
No Multiclassing for any Charisma caster (Including Paladin).
No more than 1 Multiclass per PC (and they better have a good (in game) RP reason to do so)
Variant Human attains their (free) Feat at 5th level.
Flying Races attain their flight only at 5th level (3rd might be acceptable. Not sure)
I usually play with a high charisma (12-14), but rarely play "charisma classes" so I could live with the first one, but if I liked these classes I probably would not like this rule..
