I'm struggling to find any use for the tank - it's advertised as useful for taking down the biggest territories but they're so far away from the starting point that I can't see how I'll ever be able to get any use out of it. Maybe i'm just too idle-active to benefit from it
Yeah I agree with this. The fact that the tanks has to crawl towards where its would be useful makes it inherently useless for active players.
I just counted and its 68 moves to get to Puchezhsky on Europe Huge.
While taking 3 days on EH might be reasonable for both idle newbies and noobs, anyone thats actively playing idle (which I assume is the target audience for Idle Premium) can do it in less.
But I think we should just see the tank as something aimed as a nice bonus for slow players, while the fast players can enjoy their 72 second (!!!) hospital update time instead.
