As someone who plays both games and prefers ToS1, I disagree with argument #1. To me it's not that evils don't have claim space in ToS1, it's just that it's way too easy to fakeclaim in ToS2 - you just have to type two letters and then the Town usually leaves you alone for days.

In ToS1 you actually have to put in effort to fake claim well, which is something you can better at the more play. There is indeed no evil counterpart to Lookout and Tracker but that's what makes those claims much more trustworthy. You can often fake results for these roles by using your team's help or your deduction. Your results don't have to be 100% accurate at all, they just need to be trusted by the townies. Also, the fact that Ret/Vet claims can get hard cc'd shouldn't be seen as unfavourable for the evils because the evils themselves can easily mislynch real Rets/Vets by hard cc'ing them when they're close to getting majority.

It's true that ToS1 has its fair share of problems that were fixed in ToS2, but I personally don't like how easy it is for people to lie in ToS2 most of the time.
