@Sronzer base stats will remain the same but bare in mind that we do not have all info yet.
Besides obvious upgrades you get with number of spells at your disposal and crafted and enchanted gear, we still need more info on:
racial transformations and what bonuses will they provide
number of profession items that will get added to the game and may provide further boosts (alchemy,...)
an effect of technological upgrades on humans (possible implants, and what not)
benefits of contributing to your gods (will there be any extra bonuses that we may get by working for them?)
Also, by playing longer you will make more friends, and that may also be considered a power increase compared to being solo.
