I don’t know the tiers requirement (are all the bonus gain/requirement shown anywhere? would be cool to add those on the wiki to be honest), but having infinite tiers is nice in the end, whatever the numbers are.
I see it as a “just play, and eventually you’ll get rewarded” more than “ok I need to focus on doing X oryx kill for the next tier”, which was the way it was with the old stats bonuses.
no clue what “grotesque monsters” are, but structure kills is fun, all those walls you kill are now counted, which is hilarious (those are structures, right? xD). I also wish they add “skulls killed”, since we have “cubes” already (and also, they NEED to add the infamous “sheep kills”, how come that isn’t in it already!!!)
As for the no teleporting, it was really not impressive at all, what was happening was simple, and pretty awful experience (yep, I had it the few times I fame farmed, shame on me) : you just go to the fame train realm with a fast class (not trix or ninja, since mundane too, doh), then you walk your way in that infamous circle and stay until the realm close, then rince and repeat. You also never (or once for tunnel rat) go into any dungeon, because of how much of a bother it is to not be able to teleport (since you can’t shoot either because of accuracy + god kill ratio).
If you never done that, I’m telling you, that’s definitely not something impressive, and it’s suuuuuuuch a bother to play like that, I’m very happy this isn’t a thing anymore
