I've been revisiting anno 2205, infamously the ugly duckling of the Anno series of RTS games. I don't mind so much the fact that it's different, lacks customisation and random map generation - I'm bothered because the game is so slow to progress through on challenge settings, and it feels like a game designed just to artificially waste your time; in other anno games, you can always pull tricks to dig yourself out of economic crisis - selling off assets and surplus goods, completing quests for other parties, or taking loans. 2205 is very very confined in terms of what you can do to financially recover in the early game and forces you into a lot of military events.
Because it's not particularly encouraged by the game. Like you can, they give you the tools, but theres a bunch of stuff you can get earlier with perfect parrying, or is gated behind it entirely, so you feel like you should be doing it.
Personally I found a mod to make the parry and dodge windows a little longer so I could reliably hit them, after which it became much less frustrating.
