some questions

[msp]

I need archers for dragon fighting. Should I choose elves or hunters?

Skeleton Archers. Unless you have insane amounts of Atk (30+) they are your number one choice + Dragon Arrows (even without).

No more skeleton archers, 2500 or so and i keep them for harder battles.

Current stats: level 29, 23k leadership, 3 incarnations and an army made of elves/skeleton archers, demons, royal snakes (of course ), inquisitors (of course x2 ) and knights. I cleaned all the land, there's no enemy left (i think ).

Why would you "keep" them for harder battles ? Units are there to use them. If you're in danger of running out of Skellies, just make sure you restore them before the battle ends.

Btw in combats where you see that you cannot out-dps the enemy before he starts spamming Geyser for instance it is very much advised to refrain from using non-resurrectable units or those that can't restore themselves (Vampires, Ancient Vampires, Cursed Ghosts, Inquisitors). So if anything, then it's the hard battles where you do NOT use Skellies :> Not the other way around.
