Hi there! It's been a long time.
I have only played Dwarves until then, so I'm not gonna discuss balance changes for other factions.
Still, you did a great job with Dwarves! I admit I was a little dubious but you managed well.
I am aware of the hotfix patch coming next so I'm not gonna mention bugs. However there are a few things that could be in my opinion improved and aren't planned as far as i know. For instance, - battlewagons take too much damage and should auto-heal upon lvl2 ;
- Dain (Iron Hills) is not strong enough and I find it weird that he costs almost 1000 less than his son ;
- I got it: you're gonna stick with your designs for Iron Hills and Erebor, and, after all, I'm even fine with that, concerning regular units. Indeed they're pretty good to be totally honest. But I think Iron Hills slayers and Erebor axe swingers really deserve an upgrade. There's plenty of stuff in BotFA's art.
- The spelltree could use some tweaks I think. For instance the lone tower is not unique in any way (Gondor) and doesn't fit to dwarves I believe. Also the spell 'Greed' is so hazardous it does not even seem worth it to me. I personnaly liked the vanilla 'Dwarves wealth': Dwarves are rich and need to played like that. Just like a good Isengard, sort of.
Anyway, all the other stuff (in 4.1 and to come, like Thorin's regal armor and new palantir for Erebor Dain) is great. I especially LOVE that you changed the hideous beast that used to led battlewagons by rams. My general feedback is very positive, be sure of that.
Also, I don't really know who send you what english voices, but if you desire voices from X or Y and you haven't got them yet, I'd be glad to help for the cutting.
