Do you find you encounter some of the same problems when a Druid Wildshapes into a Large creature like a Brown Bear?
How do you deal with the Enlarge spell?
The Enlarge spell specifically states that the weapons grow too, and gives a value for the increased damage. The result is PCs don't need to think about grabbing new weapons. It's a well-written effect - it lays out relevant mechanical consequences. Guardian Soul doesn't.
In the end it could just say "you receive the benefits of the Enlarge spell along with these additional effects", and that'd be pretty straightforward to adjudicate. But that's not what they wrote.
Having rules text that lets you avoid arguments with players about weapons and whatnot is indeed a Good Thing. It's very easy for players to get excited about 4d6 greatswords or whatnot, and get quite annoyed and aggrieved when they are forbidden it; just like it is very easy for a DM to be worried about balance and the daft mental image of carrying around 10ft long greatswords, and get annoyed at being made out as the bad guy when (s)he forbids it. Regardless of who is right, both sides are likely to be annoyed at the outcome. So the way that Enlarge sidesteps the issue by saying up front 'here is how your weapon damage increases' is really good, and I think something that should definitely be incorporated into any new feature that has a similar effect.
There was a rules artifact in the feat (I can't find it since my book fell apart and was replaced) but there is also the actual rule.Wasn't that just a rules artifact in the Grappler feat?
I'm not following you here. Just because the enlarge spell specifies what happens to your weapon, how do you rule if they want to carry around a 4d6 greatsword to use when they are enlarged (assuming they throw it to the ground before being enlarged and then pick it up after, because otherwise it would still be too big for you)? Since the guardian doesn't state that, it means that the weapons you are carrying aren't enlarged and therefore don't do the additional 1d4 damage.
The disadvantage with Mounted Combatant and dungeons isn't so much the Large size, but rather that horses have pretty big problems walking down stairs (unless they're specifically built for horses with a very shallow slope) and otherwise negotiating the kind of rough terrain you find in a typical dungeon.It's ironic to see everyone objecting to Large size on this thread as extremely powerful, when in the general case, if you comment on how e.g. Mounted Combatant is a very strong feat, so many people will turn right around and tell you that you can't get Large-sized mounts into adventuring locations like dungeons and that Mounted Combatant is therefore useless. Both of these things cannot be true simultaneously.
I think the point he's making is that a Large Greatsword is a Large Greatsword, and under the effects of the enlarge spell, you deal an extra d4 damage compared to medium size no matter whether the weapon grew with you or you just picked it up.[MENTION=32659]Charles Rampant[/MENTION] I agree that a creature who has been enlarged has the weapons it is carrying enlarged and that those do and extra 1d4 damage. But what if the enlarged creature picks up or carries around a weapon one size to large for it to use when enlarged as is being discussed for the Guardian? If on their person when the spell is cast, the 4d6 Large Greatsword would become a 4d6 + 1d4 Huge Greatsword, and still wouldn't be usable by the PC. If they throw it on the ground during the transformation, they could pick it up as a Large Greatsword at 4d6 but I would rule that they don't get to use their proficiency bonus on attacks, since they are not proficient with Large Greatswords.

The power the person I was responding to was Ancient Fortitude, and they were talking about entering and leaving guardian form to heal 2*level HPs each time. That's been changed to once per rest (short or long).
