CR Scaling and Loot

[Ibnshaitan1]

I have started a new thread because the issue I am raising has two points to it.

The first is to raise an idea of CR scaling for bosses or areas. Much as you can set the CR level of the final encounter in Durlag's Tower I wanted to posit the idea of being able to choose CR levels for some of the fights at the higher end. For example, the ability to choose the CR level of the Balor or Fire Giant General in Grey Peaks to make the encounters more difficult. Areas in Wyrm Forest could benefit, the Frost Giant King, White Dragon on Speartop etc. With well geared toons the fights are not challenging, and healers are rarely needed. Choosing higher CR levels for these fights could force party composition to be more inclusive of different roles with attending RP opportunities for parties that may want to attempt such a challenge.

The above idea links to the second which is loot. I personally like how the loot system is operating. But if fights did become more challenging a corresponding increase (not drastic) in loot quality for very high CR adjusted fights would be appropriate. Perhaps an increase in RG items that have multiple benefits rather than the cookie cutter items often found. To what extent the loot adjustment would make sense I leave to others. I am just floating the idea. Also, to what level of CR would be appropriate I frankly have no idea as I don't know if 35 or 40 would make the encounter impossible.
Thank you for any consideration of this idea that the DMs and community find valid.
