But you totally showed in your post what is wrong with them: Why should anyone use them if they can use a morningstar.
They may not suck but they for sure arent great. Thats not the problem. The question is why morningstar (without being op) is better then every
single option you could chose as axe.
=> Yes you are right in one point: We need a high tier 2h-Axe. It should be around 1m long to not be like a poleaxe it should be unbalanced but
it should deal incredible damage (like the persian) while not being slow (like the great axe) and it should have the secondary pierce mode (like the other persian).
That would be an axe people would consider.
Oh, the Morningstar is OP as fuck! I love it for it
And to why people should use the other axes instead? Well. Roleplay and/or upkeep. For many people those two things don't matter, but for some it does. I've always found it funny how people, when they want to save money, always lower their armour first while still having their expensive weapons. Personally I like to keep the armour and downgrade on weapons. Looting is a fun and entertaining pastime
As for a morningstar vs similarly priced axe. First of all, increase the morningstar price. It's the second most damaging weapon in the game and too cheap for it's usefulness. My thinking is that the axe should have more base damage, but cut, more reach and possibly (if it has a spike) the ability to turn over and use the spike instead of the blade. The morningstar, ought to have less base damage, but pierce/blunt, same speed and maybe knockdown. Knockdown only if the axe got the alternative mode. Maybe do as with the Iron Mace and add a polearm-animation stab for the morningstar with blunt damage? To give it the possibility of knockdown?
