Many of the favour options are signifcantly dated and could use an update.
Among them:
Agents favour that provides a dragon shard. This is almost useless now as it not longer allows respecing of feats at high level. Instead I would suggest a lesser heart of wood.
Silver Flame Favour 400 is great for the silver flame pots. But to get the lesser at the same level seems a bit backward. Allow lesser pots at 150.
1750 Favour for 32pt builds and a +2 tome. I can still appreciate the 1750 for 32pt builds, but a +2 tome? At the time of release this was something worth working for but now... How about considering the following progression:
400 Favour: Drow and +1 tome
1000 Favour: Veteran and +2 tome
1750 Favour:32 pt builds and +3 tome
I suppose you could make the +3 tome more favour but...
The only issue that TR's could TR 6 time for a +3 to all stats. But personally if someone is going to do that then they have earned it.
I much prefer to be able to work toward things then lottery based loot. This maybe the result of the last 8 or 9 20th raid lists getting jack. But I would like to see things such as the tome of legends developed for end game. At least you can trade stuff. An example would be tome of might which could require 8 pages dropped from Shavarath quests that unlock and item or tome.
Just some thoughts...
