Three questions about leveling

[Spacehamster]

Hello :)
I have 3 questions about leveling toon/units:

- If battles get too hard, is there a way to get additional exp? Not by doing side quests, but
some sort of grinding by replaying battles for example?

- I noticed that my 2 favourite unit type are max lvl in this zone. Should I switch to my
other unit types to give them experience too or is it ok to stick with the units I prefer to play
with?

- I'm trying not to use the champion units because they're limited. So far I haven't used any,
but now they're all low lvl. Will I get in trouble at higher lvl?

Thanks,
- Kassad

- There dungeons (you can recognize them by plate with crossed swords near entrance) where you can be ambushed after movement to the new "circle". If you'll not respond on occurred quicktime event, then the battle begins. Also these zones with ambushes can be found outside of dungeons, if i remember correctly, in each campaign.
- Only if you need achievment (raise all units in one of the campaigns to lvl 5), otherwise, no, you shouldnt.
- Nope, but depends on luck. There comes little offtop. Let's compare. Lucky start with champion units (4x square) = 100% win, while lucky start without them or with 2x square champion units = 90% win. Something like that. And i am talking about battles vs AI. Cant say anything about battles vs human, because i didnt try it yet (maybe someone want to try it out?).

Thanks for the reply! :)
I'm such an idiot, never even tried to equip the champion units because I thought it used a core unit slot and they're limited, so I missed alot of exp for these. Restarted the game and I'm leveling all units now, it's far more easy to play with the champion units on the battlefield (so far). I like the game even more now :)
