Well I soldiered on and there hasn't been any improvement. For example, a Cave Bear den on turn 115 gives 9 XP to a hero with potential and tutelage. A level 12 Forest Drake with three Pack Drakes yields 33. Capturing a city with an Epic defense = 21. Leveling up has been reduced to a crawl, my sovereign is getting far less experience on his own than with a champion in LH 1.6. Playing with two heroes in the same stack is simply no longer a viable option. As a result of the XP trickle, the majority are now only fit to sit in towns to reduce unrest. The champion system and its RPG elements probably make 90% of the game for me and as it stands in the beta, it's missing one of its support pillars.
Turn 329 with Ineluctable Vision active, 12 opponents left. The AI champions are also suffering from the lack of XP. Looking at the [Fame 3/Level 1 champions], their respective levels are 6, 7, 7, 7, 8, 8, 8, 8, 9, 10, 10, 10. Three have 10+ injuries, one has a whoppin' 12 (!), something I've never seen and no, I didn't inflict any of those. Oy.
I'm finding the rewritten battle ranking system to be much more in tune with what experience you should be getting. Easy fights = not much XP. Makes sense to me.
Sure, there may be some fights that are too easy....but those fights have always been too easy.....shouldn't be getting free or near-free experience from it.
I completely disagree because it's not being compensated later on, experience doesn't scale. The less you get at the beginning is not being balanced by getting more later on, comparatively speaking with LH 1.6. Clearing monster lairs for such diminishing returns, especially after playing this game since the FE days, is frustrating beyond words. And maybe I'm the lone voice in the night since I'm the only one complaining.

And yes, there is always modding to soothe our woes.
