I didn't read all the pages in the discussion but I really don't see a convincing argument for why the same tome scaling effect as LR and GR shouldn't be applied. And there are definite sound arguments for why they should be applied, in-game wise and lore wise.
Lore wise, tomes represent knowledge! Its not as though these characters get wiped clean from their previous life. This is evident from PL feats.
Now, in-game wise I don't see an adequate response to why people should be punished for eating tomes; especially the rare variety such as the +3 and +4 tomes.
This currently implemented system punishes the players who ate tomes before TRing existed. I don't see why Turbine punishes the players who have played for longer and are more likely to want to TR.
For the rest of the DDO community, I don't see why people would want tomes at all if you have any desire to TR in the future. Seeing how the end game currently involves epics (which usually means you're looking for gear) and TRing, I feel that tomes have become something of a trap.
Certainly, one might think that its fine as long as you pull the same tome for the same stat you'll be fine right? Its easy to say, grind em out! But why should you have to grind for them AFTER you TR when you didn't need to recraft your GS items?
I can't think of a reason and don't know why Turbine is punishing players like this.
If anyone can enlighten me, that'd be great!
