I agree that df2014 gobs are pathetics and they're attacking so rarely and in so small numbers that you can only lose a battle if you field new untrained or naked dwarves.
And let's not talk about adventure mode in which you can slaughter goblins by thousands without most of them even trying to fight back.
But past versions gobs (34.11 and earlier) often fielded several weaponmasters along them , and they were real troubles, not pushovers like they are now, weaponmasters were quite much as strong as legendary dwarven warriors.
Now undead, they're indeed broken as in simply not fun or interesting challenge, if your fort get an undead siege, what are your options if you want to continue your fort
- just turtle in and ignore the undead
- you have made tons of traps to catch them all
If you choose to meet them on the field to have some epic battle like in past versions (in which the power of undead was in their huge number and re-animated bodyparts as they were falling+ re-animating of your own dwarves when they were overwhelmed) , a single undead is able to one punch your legendary through its armor, chip the bone resulting in him getting unconscious and of course dead some turns later, that's not really leading into better story.
In adventure mode,
multi attack is so overpowered that you can take
several dozen of undeads around their necro tower by yourself if you apply that multi-attack
accuracy exploit, and if you try regular fight, at some point one of the undead will punch you through your nice armor and chip a bone -> direct unconsciousness, then of course dead.
Again, it does not contribute to any better story.
Hopefully goblins and undead will get some really good rebalance.
