I was just thinking about the Dragon Dieties and their escorts/guards/whatever and what the CRs mean in v5.
So Bahamut has his 7 Great-Wyrm Gold Dragons and poor Tiamat only have 1 Great-Wyrm of each of the 5 colours she represents.
So Bahamut was stated to be CR 107 which according to v5 means he is a EL 27 encounter.
Tiamat at a mere CR 98 is however, still EL 27.
7 GW Gold Dragons have total CR of 483 which gives them an EL of 31.
A GW of each Chromatic Dragon has a total CR of 302, which means they have an EL of only 29.
So this means that you're going to have a significantly harder time taking down the few dragons guarding these gods than the gods themselves, or alternatively that the guards of the Gods should be have atleast a 3 in 4 chance of defeating the gods they guard.
This seems a little silly that a handful of GW dragons should be able to consider their GODS at a mere Difficult encounter. So either the Dragons as stated by UK from v5 have a too high CR for what they can do, or the Dragon Dieties need a higher CR(EL+4-5?), or perhaps Dragons shouldn't really fear their gods.
A single GW Red/Gold/Silver Dragon would consider Bahamut or Tiamat a mere Very Difficult Encounter.
