Partner Content Clarity

You need to either clearly label partner conent as 3rd party/unofficial -or- make sure it is balanced with official content. 

Right now I am seeing Grimhollow subclasses listed on the core class pages right along side official PHB subclasses with zero indication that they are anything other than official content, which is highly misleading.  Grimhollow is cool and all, but it is most definitely not balanced the same way official WotC subclasses are.

What's particularly frustrating about this is that when they first started including third-party content on those pages — with the first round of Critical Role stuff back in the day — there was a huge banner above each third-party subclass that warned you it was third-party content and told you what the source was. You can still see this on a few of the old ones, but at some point they just...stopped doing it for no obvious reason.

All the partnered content is at the bottom of a class page, alphabetically sorted.

It's fairly easy to deduce that it is such.

Likewise, balance has not been part of 5th edition whatsoever because High Elf Wizards who primarily cast Hypnotic Pattern, Fireball(& its variants) & Wish(Most things in DND nowadays are scaled to these) still aren't nerfed to match low-strength Halfling Barbarians in heavy full plate armor who use blowguns.
