well i got i to work finally after a re-install
Well in the beginning you would be OP but later on the stages it doesn't really matter
the beginning is rididoulously hard without this mod
Only managed to do a no-loss 2 times out of 50 on the starting island lol
after the first island it's getting easier and easier imho since u get better unit selections and the main part will still be raping the undead(for more than 180 battles or something
before u get to the next quest boss(the spider)
I find WOTN alot easier after the first island that the previous installments
but back on topic to your question
I think it makes a minor difference later in the game since u would then have the possiblity to use other troops anyway so
The only thing that could be a bit of a hassle is that on later stages the troops don't get that much of quantities
but to be honest i just cannot be arsed to take this game seriusly
the beginning is way too hard(i mean lol 3 bosses in a row?)
it's doable but u have to be very lucky with the RNG
in the beginning of the game (4first islands will be mainly about killing undead troops)
which to me is a total bore but thanks to this mod u can steamroll it and get to the more interesting parts without too much hassle
it's a matter on convience (u could also use this mod just to get off the first island and just go with a viking build like the game attended so you wouldn't reallt feel a difference)
just my 2 cents
elaborate enough? xd
