I exit that discussion. It's like trying to explain why a soccer match must be won within 90 minutes. Like Baalz said, this is the rule of the game, play keeping it in mind. No, let's change it! As the shoes are becoming better, players can run for 180 minutes, this will keep the game alive for years, not its flavour. If your team doesn't have anybody in attack, but everybody in defence, the match should not finish until you have done all the goals you need to win.
You can't lose a mindless SC because of the turn limit. You can even let him with just a 1dmg attack only, firepower is a useless addition. Just keep him with high regen and defense, he must fight for possibly 200 turns in just one month, if nobody is able to kill him he should never stop working - even if being mindless gives him only the disadvantage of being unable to route and plenty of advantages.
Next thing to change: the Rituals. That's "illogic" a mage casting one ritual in one month, not a rule of the game, that's a "boundary"! You can't plan your strategy around this, this has to be changed. Mages should cast as many ritual as the PC, becoming always more powerful, lets you do before imploding.
Sorry, I just became tired of this
It just doesn't seem me this big problem, but for many is so, and still can't understand why, it makes perfect logic into the game mechanics.
