Educated is kind of a very RP focused sort of perk, and its bonuses are fairly low priority for a rogue, being what is essentially SF (Lore) and a very, very small XP bonus for succesfully translating even very high lore checks.
However, the fact that you don't take 20 on a lore roll means that often times even low DC lore things can go unlored, despite having a less the 5 difference between the skill bonus and the DC (I'm speaking from personal experience on this ;D )
As such, perhaps as a pure bonus for rogue with educated, they could be allowed to get a free reroll on any lore checks they fail, to show that as an educated person they have the training to go back and try to analyze what they failed to understand before? Given the largely fluffy nature of this, and the fact that educated is to many a "wasted" perk, it would still largely be unpicked, it doesn't make that big a difference, but it does make playing a scholarly/archaeological rogue more appealing.
Given that lore granting items usually also dont grant stats useful to a rogue and given the I expect highly unused aspect of this perk I'd totally be for a buff, but then some perks are purely for flavour.
Fortune teller, for example
Honestly, this perk is fine IMO. I never experienced the "EXP Gain from Translating texts" on my PC who had it, but... Lore is important for a lot of very specific things inside the module and it's hard for roguish types to get a lot of it. It's also not strictly for pure rogues, which is nice.
You're getting a feat basically for free, I think it's pretty good!
