Took me a little bit of time to make some sense of these particular guest comics, but I began reading Friendship is Dragons, and I loves.

this is so true
we broke pathfinder by level 2
best one bard - animate rope
by level 6 we made a ship fly with it

That sounds about right. System is evenot easier to break then 3.5 which is saying something.

Easier, yes.
But 3.5 could be broken much much much much much much much much much much (etcetera etcetera ad naesum) more throughly

For an easy and visible comparison, there is no pathfinder pun pun analogue.
In 3.5 pun pun and things like him could be done in a half a dozen ways.

Pathfinder also lacks such insanities as epic spells with a negative spell craft DC,

Pathfinder doesn't have planar shepards, archivists, precocious apprentice, locate city bombs, or anything from frost burn book vows of poverty or anything

I watched the episodes where she appear not long ago, and i thought: wait what? A giant who can grow smaller while keeping giant level of strengh?
that mini mini no mi would have been neat in the hand of a human, but a giant with that power? that's really OP for a filler character.

RP wise, guess it'll leave her to grapple with anything without neading any aditional feats..
