Because when it's not "training wheels", it's "noobs", or "There is really no valid argument for otherwise"... Do you realise how condescending that sounds ?
Look, no-one (I think) disputes the facts that:
- Level 1 is supposed not to be too complex.
- Complexity rises throughout the whole game.
But that is all that there is to it. For CHARACTERS, there are tiers of play, about the usual influence that they can have over the setting.
But because this is all that there is to it, everything else like assuming that a range of level is more "beginner friendly" than another as well as naming that is purely yours. I'm just telling you that it's not the case by design of the game (the tweets speak about level 1 only), and that the condescension that you show about naming these ranges (which, once more, exist only for you) is not acceptable.
