Agreed! The whole weapon unlocking mechanism both melee and missile is flawed/not fun. I would like to see all basic weapon types unlock at a earlier in the tech tree and then give us incrementally improved versions or improved troop tactics through tech.
I would argue that the multiple unlockable buildings in the fortress cities line are super annoying busy-work. The fortress, dedicated to pumping out troops, should get those buildings/bonuses AUTOMATICALLY.
edit: interrupting troop building to get +2 defense, -25% cost etc. is busy work. end edit.
Let your interesting decisions for the Fortress come at level-up. Save building decisions for the Towns and Conclaves and give them more cool branching paths. Also, potions available only at Ye Olde Magick Shoppe in my one conclave city is {yawn}. I could have a low level hero fetch it, but meh.
Also, Kenata in E:WOM had a great mod that would let an archery unit give all enemy units in a 3x3 or 4x4 area a volley of arrows once every 3-5 turns.
So good point and on to 1.13!
