Yeah, that channel is primarily by and for people who prefer 3.8.1, as 4.0 was probably our most divisive version yet. But to each his own
When we reduce unit health, the damage of heroes (and most other things) will stay the same for now. After all, the whole point is that stuff will die faster
And from what I've gathered, giving hero powers some more impact wouldn't go amiss. We don't want them to be as powerful as they used to be (units that cost 1000 or more
shouldn't get oneshot by a single spell), but there's still room in between. If particular aspects turn out to be too strong with less health, we'll adjust them accordingly. Archer spam is what I'm probably most concerned about here, but with the Lorien release we'll have plenty of opportunity to see archers at their strongest and gauge their power.
Hero health, however, is another matter, and that's still up in the air. At the moment, I'm more inclined to leave it as it is for now and see how it goes. If it's too high, we can adjust it afterward, but I got the impression that right now hero health is already considered rather low. If they always die first like EliteKryptik said, bringing down units a bit and leaving heroes the same should balance things a bit.
Buffing heroes armor against fire arrows is ok, but please don't increase their resistance against regular arrows. Standard archers barely do no damage to heroes.
We'll start with just a buff against upgraded arrows then
How much armor would you say is reasonable?
As for Isengard and Mordor, they are meant to become more powerful as the game goes on, but there should never be a point where you've basically won by default because you have survived long enough. If that's the case, we'll have to nerf the lategame of that faction. That's not really a discussion for this thread though.
